Organic Polymers Modified with Inorganic Polyhedra

摘要

Nano-sized inorganic clusters(POSS) can be successfully incorporated into a wide variety of different organic polymers. These POSS clusters cause increases to the thermal transitions and mechanical properties of the polymers they are copolymerized into. Not every POSS is the same and the POSS effect on the properties of analogous polymers shows a dependency on the type of alkyl group on the POSS cluster. Rheology of high molecular weight PDMS grafted with small amounts of POSS illustrates a dependence on both the POSS-alkyl-group and POSS shape. TEM images of randomly copolymerized polymers illustrate this dependency, as the size of the POSS domains are alkyl-group dependent.
