The work is focused on the modification of the brittle epoxy matrix by
silicone elastomer with a view to improve the toughness characteristics without
significant reduction of modulus, glass transition temperature and interfacial
adhesion, and, to obtain conductive nanocomposites. The emphasis has been put
on the preparation technology of epoxy-silicone polymer system with controlled
morphology and mechanical properties. To this end, epoxy resins based on
diglycidyl ether bisfenol A and different types and content of
polydimethylsiloxanes were mixed. Curing was carried out using
diethylentriamine hardener and dicumyl peroxides as compatibilizator. These
blends were subsequently filled with carbon black or carbon nanotubes to obtain
electroconductive systems. It has been es ished that mechanical properties of
such nanocomposites are influenced by the microstructure of the multiphase
system, which in turn is determined by the presence or absence of interphase
compatibility between two polymer phases. The electrical properties of
nanocomposites heavily depend on filler aspect ratio, filler content, and, to some
extent, on polymer matrix composition. Aforementioned types of conductive
materials can be used as conductive adhesives, electromagnetic interference
(EMI) isolation materials, antistatic coatings, etc.
