rheological behavior of poly(lactic acid)/ silicon rubber/ silicon modified graphene oxide

A novel thermoplastic vulcanizate (tpv) material consisting of poly(lactic acid) (pla) and silicone rubber (sir) in the presence of  silicon modified graphene oxide (simgo) was fabricated using dynamic vulcanization, which is broadly applied in various fields due to their excellent performance, such as remarkable mechanical properties. the as-prepared tpvs possessed good mechanical properties, elasticity, and easy processability. more importantly, in situ interfacial compatibilization between the pla and sir phases was induced by dicumyl peroxide (dcp).fe-sem shows that tpv containing 3phr of simgo has higher uniformity than other samples.
