Inorganic-organic hybrid polymers matrix materials

In the field of composite materials, inorganic-organic hybrid polymers offer great promise as precursors to ceramic matrix materials. In these applications, high purity ceramics are often not necessary and preceramic polymers allow the introduction of inorganic elements such as silicon and boron in quantities which can be directed by polymer structure and stoichiometry. [Pg.236]

Another approach to improve the separation characteristics of a membrane is the implementation of additives. MMMs consist of an inorganic or inorganic-organic hybrid material in the form of micro- or nanoparticles (discrete or dispersed phase) incorporated into a polymer matrix (continuous phase) (Figure 3). ... [Pg.406]

Silica hydrolysis-condensation of alkoxysilane-terminated chains of various polymers (PB, poly(propylene)-glycol, poly (ethylene)-glycol) leads to the formation of silica nodules. Hybrid (organic-inorganic) nanocomposite rubbery materials are obtained in this way. These materials have been swollen by various deuterated solvents, in order to probe the order induced in the polymer matrix under stress [80]. [Pg.584]

Hybrid Sol-Gel Photopolymerization Photosensitive organic-inorganic sol-gel glasses are interesting alternative materials that combine the properties of glasses and polymers [316]. A typical hybrid sol-gel material consists (10.88) in an acrylated silane derivative (which in a first step, leads to a glass-like material via hydrolysis and condensation) and a photoinitiator that allows the free radical photopolymerization of the acrylate. The requirements for the choice of the photoinitiator in such a matrix are crucial solubility, thermal stability, PH compatibility, polarity, and so on. [Pg.405]

Layered silicates dispersed as a reinforcing phase in polymer matrix are one of the most important forms of hybrid organic-inorganic nanocomposites. MMT, hectorite, and saponite are the most commonly used layered silicates. Layered silicates have two types of structure tetrahedral-substituted and octahedral substituted figure 6. In the case of tetrahedrally substituted layered silicates the negative charge is located on the surface of silicate layers, and hence, the polymer matrices can react interact more readily with these than with octahedrally-substituted material. [Pg.275]
