inorganic polymers wikipedia

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 … In chemistry, catenation is the bonding of atoms of the same element into a series, called a chain. One of the best known examples is polydimethylsiloxane, otherwise known commonly as silicone rubber. [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. Polyphosphate (PolyP) is an inorganic polymer made from phosphate subunits. The premier materials are polysilanes, which are analogous to polyethylene and related organic polymers. See also . The compound is isoelectronic and isostructural with benzene. 2.27.2.2.3 Analysis of inorganic coatings on polymers. Most polymers (a category that includes all plastics and rubbers) are organic, synthetic, or semi-synthetic compounds. Français : Les polymères inorganiques sont surtout représentés par les silicones , qui … There exist a sizable number of phosphorus polymers with backbones ranging from primarily phosphorus to primarily organic with phosphorus subunits. More precisely called polymerized siloxanes or polysiloxanes, silicones consist of an inorganic silicon–oxygen backbone chain (⋯−Si−O−Si−O−Si−O−⋯) with two organic groups attached to each silicon center. Both the IUPAC and Chemical Abstracts Service (CAS) make similar naming recommendations for the naming of polymers. [12] They biodegrade into a near-neutral pH mixture of phosphates and ammonia that has been shown to be non-toxic, and the rate of their biodegradation can be tuned with the addition of different substituents from full decomposition within days with glyceryl derivatives, to biostable with fluoroalkoxy substituents. Typically two types of atoms alternate along the main chain. In polymer science, the backbone chain of a polymer is the longest series of covalently bonded atoms that together create the continuous chain of the molecule. Mark, J. E.; Allcock, H. R.; West, R. “Inorganic Polymers”, Prentice Hall, Englewood, NJ: 1992. Usually not classified with charge-neutral inorganic polymers are ionomers. 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. Tetrahedral molecules can be chiral. Silsesquioxanes are members of polyoctahedral silsesquioxanes ("POSS"), which have attracted attention as preceramic polymer precursors to ceramic materials and nanocomposites. Wikipedia Citation. However, certain inorganic and inorganic-organic polymers, for example those containing metallocene derivatives, are at present best named using organic nomenclature, e.g., the polymer shown can be named poly[(dimethylsilanediyl)ferrocene-1,1'-diyl]. [6] Pyrolysis of poly(dimethylsilane) gives SiC fibers. An inorganic polymer is a polymer with a skeletal structure that does not include carbon atoms in the backbone. Media in category "Inorganic polymers" The following 21 files are in this category, out of 21 total. They are more fragile than the organic analogues and, because of the longer Si–Si bonds, carry larger substituents. They are mainly of theoretical or academic interest. Silicone rubbers are widely used in industry, and there are multiple formulations. A polymer is a large molecule (Macromolecule) composed of many repeated subuints called (monomers). English: Inorganic polymers are mainly represented by silicones, which consist of -Si-O- repeating units. Common backbones utilized in SIPs include polysiloxanes, polyphosphates, and polyphosphazenes, to name a few. Similar hybrid textile coatings made of amino-functionalized polysiloxane with TiO2 and silver nanoparticles have been reported to have smart stain-repellent yet hydrophilic properties, making them unique in comparison to typical hydrophobic stain-repellant coatings. English (wikipedia polyethylene) Noun (organic compound) A polymer consisting of many ethylene monomers bonded together; used for … This chemical reaction is useful in the organic synthesis of organic compounds.
