In Situ polymerization of propylene with carbon nanoparticles. Effect of catalytic system and graphene type

Two catalytic systems, metallocene-based and Ti-based were used to synthesize by in situ polymerization the composites of polypropylene and few-layer graphene nanoparticles, prepared by chemical or thermal reduction of graphite oxide. The effect of metallocene and titanium catalytic systems on the properties of nanocomposites and distribution of nanoparticles in polymer matrix is investigated in detail. The data on electrical and thermal properties of nanocomposites are presented. POLYM. ENG. SCI., 2017. © 2017 Society of Plastics Engineers
