Abstract
Effect of carbon nanomaterial on the thermal stability of photochemically treated polydimethylsiloxane materials doped with this carbon nanomaterial was studied. It was demonstrated that even the introduction of a small amount of carbon nanomaterial into high-molecular polydimethylsiloxane rubber SKT causes a substantial increase in the thermal stability of photochemically hardened polymer during thermolysis both in the inert atmosphere and in the air. This is assumed to be connected with its participation in suppression of destruction processes. The mechanisms of thermal and photochemical processes taking place in the polymer matrix are proposed.
