TESTING FULLERENE SOOT AS ANTI-OXIDATIVE AGENT FOR POLYDIMETHYLSILOXANE RUBBER
Journal Title: International scientific journal Science and Innovation - Year 2023, Vol 2, Issue 12
Abstract
Fullerenes have intrinsic high electron affinity and they are therefore capable of acting as radical traps in free radical chain reactions, including polymerization and the thermo-oxidative degradation of polymers. Reactivity of fullerene particles in polymer mediums is governed by diffusion and promotes active termination of oxidation chains on macro-R• radicals. Radical accepting capacity of fullerenes is comparable with that for well-known commercial primary stabilizers. Therefore, cheap fullerene matters even unpurified samples could be used for stabilization of polymer materials. To check this postulate, the anti-oxidative activity of fullerene soot has been studied as agents preventing thermo-oxidative disruption of siloxane rubbers. Polydimethylsiloxane (PDMS) – C60 (soot) composites was prepared and tested on thermo-oxidative stability. The fullerene soot additives increase all temperature points of the degradation and can serve as effective anti-oxidative agents for the rubbers
