Hybrid interpenetrating network

Hybrid versions of silicone-thermoplastic semi-IPNs have been developed (19). A hybrid interpenetrating network is one in which the cross-linked network is formed by the reaction of two polymers with structurally distinct backbones. Hydride-functionalized siloxanes can be reacted with organic polymers with pendant unsaturated groups such as polybutadienes (5) in the presence of platinum catalysts. Compared with the polysiloxane semi-IPNs discussed earlier, the hydride IPNs tend to maintain mechanical and morphologically derived properties, whereas properties associated with siloxanes are diminished. The probable importance of this technology is in cost-effective ways to induce thermoset characteristics in thermoplastic elastomers. 

Physical hybrids containing silica and polymer are typically interpenetrating networks (IPNs). They can be subdivided into simultaneous or sequential IPNs. The terminology of... 

One of the principal features of the compounds discussed above is their ability to be transformed into final products and/or articles from mixtures of almost any composition, even those whose components have little compatibility. The use of oligomers and monomers of various chemical structures expands the assortment of materials and articles that can be produced by combining different components. The interest in so-called hybrid binders, interpenetrating networks, polymer-oligomer systems, and other possible reactive components has increased during recent years. 

Our study shows that solvothermally synthesized CdTe nanoparticles can be easily embedded in MEH-PPV matrix. This work provides an initial path to design a hybrid absorbing layer for solar cells. The incorporation of nanoparticles into polymers requires optimization of blend morphology using solvent mixture to get continuous interpenetrating network.

Hybrid Photopolymerizations. Hybrid resin systems consist of monomers possessing two different functional groups—one that photopolymerizes by a tree-radical active center (such as an acrylate) and the other by a cationic active center (such as an epoxide) (85,106-109). The two functional gronps may be combined in one formulation either as separate monomers or as one monomer with both functionalities. If the functional groups are on different molecnles, entangled chains or interpenetrating networks will be produced cross-linked stmctnres will result if the functional groups are on the same molecule because the polymer chains can be connected via either reactive bond.
