Inorganic Polymers: Backbone constituted by elements other than carbon.On the basis of their synthesis: 1. A special class of inorganic polymers are geopolymers, which may be anthropogenic or naturally occurring. Smart inorganic polymers (SIPs) are hybrid or fully inorganic polymers with tunable (smart) properties such as stimuli responsive physical properties. On the basis of their synthesis: Natural Polymers; Synthetic Polymers; Biodegradable Polymers. Organic compounds are carbon-based compounds.Organic compounds contain carbon bonds in which at least one carbon atom is covalently linked to an atom of another type (usually hydrogen, oxygen or nitrogen).Most polymers are organic compounds. Inorganic polymers can also be named in accordance with inorganic nomenclature, but the seniority of the elements is different from that in organic nomenclature. A polymer (/ ˈ p ɒ l ɪ m ər /; Greek poly-, "many" + -mer, "part") is a large molecule, or macromolecule, composed of many repeated subunits. [4] The term inorganic polymer refers generally to one-dimensional polymers, rather than to heavily crosslinked materials such as silicate minerals. The materials can be cyclic or polymeric. 2. Inorganic polymers are polymers whose repeat units use chemical elements other than carbon, although several such materials also contain carbon atoms. This 'smart glass' is capable of reducing light transmission from 57% to 28% in under 1 second, a much faster transformation than that of commercially available photochromic lenses.[13]. mər] (inorganic chemistry) Large molecules, usually linear or branched chains with atoms other than carbon in their backbone; an example is glass, an inorganic polymer made up of … If hydrocarbon substituents are bound to the silicon atoms, the polymers are designated as Organopolysilazanes. English: Inorganic polymers are mainly represented by silicones, which consist of -Si-O- repeating units. They are mainly of theoretical or academic interest. Examples are Krogmann's salt and Magnus's green salt. While organic polymers are often petrol-based, the backbones of SIPs are made from elements other than carbon which can lessen the burden on scarce non-renewable resources and provide more sustainable alternatives. Due to these properties and its ease of manufacturing and shaping, silicone rubber can be found in a wide variety of products, including: voltage line insulators, automotive applications; cooking, baking, and food storage products; apparel such as undergarments, sportswear, and footwear; electronics; medical devices and implants; and in home repair and hardware with products such as silicone sealants. The parent siloxanes include the oligomeric and polymeric hydrides with the formulae H(OSiH2)nOH and (OSiH2)n. Siloxanes also include branched compounds, the defining feature of which is that each pair of silicon centres is separated by one oxygen atom. Trihydridoboron, also known as borane or borine, is an unstable and highly reactive molecule with the chemical formula BH3. [14] These desirable properties can range from self-repair of oxidation, to sensing, to smart material self-assembly, as discussed below. These materials are highly branched structures and have chemical elements other than … A polymer is a large molecule (Macromolecule) composed of many repeated subuints called (monomers). The key difference between organic and inorganic polymers is that the organic polymers essentially contain carbon atoms in the backbone whereas the inorganic polymers do not contain carbon atoms in the backbone.Furthemore, most of the organic polymers are simple structures. [7] This particular phenomena is promising in the field of monument preservation. Poly(dimethylsilane) is prepared by reduction of dimethyldichlorosilane. An inorganic compound is typically a chemical compound that lacks carbon–hydrogen bonds, that is, a compound that is not an organic compound.However, the distinction is not clearly defined and agreed upon, and authorities have differing views on the subject. Some polystannanes such as (SnBu2)n and (SnOct2)n have shown the smart ability to align themselves with external stimuli, which could see them become useful for pico electronics. They are mainly used industrially as precursors to silicon carbide. According to IUPAC recommendations , [2] [3] macromolecules refer to the individual molecular chains and are the domain of chemistry . In terms of the composition of the main chain, they are classified as homochain polymers ([—M—] n ) and heterochain polymers ([—M—M’—] n or [—M—M’—M”—] n ), where M, M’, and M” are various atoms. He shared the Nobel prize in chemistry with Georg Wittig in 1979 for his pioneering research on organoboranes as important synthetic intermediates. [6] This action was attributed to the polymer's ability to retain the ibuprofen above the lower critical solution temperature (LCST), and conversely, to dissolve below the LCST, thus releasing the loaded ibuprofen at a given, known temperature. Polymeric forms of the group IV elements are well known. Inorganic polymers, like organic polymers, are classified according to spatial structure as linear, branched, ladder, and crosslinked (two- and three-dimensional). Many inorganic polymers also are found in nature, including diamond and graphite. CSIRO ScienceImage 10869 Researching new HIPS coatings.jpg 2,362 × 3,071; 2.18 MB. Inorganic polymers are polymer materials that have no carbon atoms in the backbone. An inorganic compound is typically a chemical compound that lacks carbon–hydrogen bonds, that is, a compound that is not an organic compound.However, the distinction is not clearly defined and agreed upon, and authorities have differing views on the subject. [2][3] As compared to organic polymers, inorganic polymers in general possess improved performance and environmental compatibility (no need for plasticizers, intrinsically flame-retardant properties). Polymers containing inorganic and organic components are sometimes called hybrid polymers, and most so-called inorganic polymers are hybrid polymers. Polymer chemistry is a sub-discipline of chemistry that focuses on the chemical synthesis, structure, and chemical and physical properties of polymers and macromolecules. Examples include polydimethylsiloxane (PDMS, (Me2SiO)n), polymethylhydrosiloxane (PMHS (MeSi(H)O)n) and polydiphenylsiloxane (Ph2SiO)n). Both are composed of carbon.In diamond, carbon atoms are linked in a three-dimensional network that gives the material its hardness. Both the IUPAC and Chemical Abstracts Service (CAS) make similar naming recommendations for the naming of polymers. See also . Each such chemical has at least one silicon-chlorine bond. A siloxane is a functional group in organosilicon chemistry with the Si−O−Si linkage. Commonly, the organic groups are methyl. This type of reaction is illustrated by the stepwise conversion of ammonia borane to discrete rings and oligomers, which upon pyrolysis give boron nitrides. They exhibit distinctive optical and electrical properties. Silicone rubbers are widely used in industry, and there are multiple formulations.

While metals are not typically associated with polymeric structures, the inclusion of metal atoms either throughout the backbone of, or as pendant structures on a polymer can provide unique smart properties, especially in relation to their redox and electronic properties. Carboranes are electron-delocalized clusters composed of boron, carbon and hydrogen atoms that may also contain other metallic and nonmetallic elements in the cluster framework. Organic Polymers: Carbon backbone. [14] One such example is a thin film of a polystyrene-polyferrocenylsilane inorganic-organic hybrid copolymer that was found to be able to adsorb and release ferritin with the application of an electrical potential. The bond lengths are 146.0 pm for a Si–H bond and 233 pm for a Si–Si bond. Smart inorganic polymers (SIPs) are hybrid or fully inorganic polymers with tunable (smart) properties such as stimuli responsive physical properties (shape, conductivity, rheology, bioactivity, self-repair, sensing etc.). Media in category "Inorganic polymers" The following 21 files are in this category, out of 21 total. Typically two types of atoms alternate along the main chain. All contain tetrahedral silicon and terminal hydrides. Polymers containing inorganic and organic components are sometimes called hybrid polymers, and most so-called inorganic polymers are hybrid polymers. Silicone rubber is generally non-reactive, stable, and resistant to extreme environments and temperatures from −55 to 300 °C while still maintaining its useful properties. Silicones are used in sealants, adhesives, lubricants, medicine, cooking utensils, and thermal and electrical insulation. Silicone rubbers are often one- or two-part polymers, and may contain fillers to improve properties or reduce cost. In chemistry, catenation is the bonding of atoms of the same element into a series, called a chain. Some of these have been shown to possess smart properties, and are largely of-interest due to the biocompatibility of phosphorus for biological applications like drug delivery, tissue engineering, and tissue repair. Synthetic polymers are generally categorized as inorganic polymers or organic polymers. IUPAC Polymer Nomenclature are standardized naming conventions for polymers set by the International Union of Pure and Applied Chemistry (IUPAC) and described in their publication "Compendium of Polymer Terminology and Nomenclature", which is also known as the "Purple Book". Inorganic polymers offer some properties not found in organic materials including low-temperature flexibility, electrical conductivity, and nonflammability. Silicone rubber is an elastomer composed of silicone—itself a polymer—containing silicon together with carbon, hydrogen, and oxygen. The principles and methods used within polymer chemistry are also applicable through a wide range of other chemistry sub-disciplines like organic chemistry, analytical chemistry, and physical chemistry. Polymers containing inorganic and organic components are sometimes called hybrid polymers, and most so-called inorganic polymers are hybrid polymers. [5], Boron–nitrogen polymers feature −B−N−B−N− backbones. Polyphosphate (PolyP) is an inorganic polymer made from phosphate subunits. Both are composed of carbon.In diamond, carbon atoms are linked in a three-dimensional network that gives the material its hardness. Molecularly, polysilazanes are isoelectronic with and close relatives to Polysiloxanes (silicones). [16], Icosahedral boron is a geometrically unusual allotrope of boron, which can be either added as side chains to a polymer or co-polymerized into the backbone. [1] While organic polymers are often petrol-based, the backbones of SIPs are made from elements other than carbon which can lessen the burden on scarce non-renewable resources and provide more sustainable alternatives. [14] Variants of polyferroceylsilanes have been found to exhibit smart self-assembly in response to oxidation and subsequent smart self-disassembly upon reduction, as well as variants which can respond to electrochemical stimulation. Thompson, in Polymer Science: A Comprehensive Reference, 2012. The preparation of borane carbonyl, BH3(CO), played an important role in exploring the chemistry of boranes, as it indicated the likely existence of the borane molecule. The polymers which are degraded and decayed by microorganisms like bacteria are known as biodegradable polymers. Polysilanes are organosilicon compounds with the formula (R2Si)n. They are relatives of traditional organic polymers but their backbones are composed of silicon atoms. [19] Multiple polymers with ferrocene side-chains cross-linked with glucose oxidase have shown oxidation activity which results in electrical potential in the presence of glucose, making them useful as glucose biosensors.
