Localization of Poly(glycidyl methacrylate) Grafted on Reduced Graphene Oxide in Poly(lactic acid)/Poly(trimethylene terephthalate) Blends for Composites with Enhanced Electrical and Thermal Conductivities

Interfacial localization of conductive fillers in a cocontinuous immiscible polymer blend is an efficient way improving the electrical and thermal conductivities composite. Conductive path formation at interface structure expected to provide high conductivity by smaller amount filler, which can be used for applications as materials. In this study, biobased poly(lactic acid) (PLA) was blended with poly(trimethylene terephthalate) (PTT) make blend. Poly(glycidyl methacrylate) (PGMA) grafted on reduced graphene oxide (rGO) PGMA-grafted rGO (rGO-PGMA). The epoxy group GMA rGO-PGMA reacted end groups both PLA PTT localized between two-step blending procedure form PTT. From transmission electron microscopy observation, it found that Both composite were improved, confirmed volume resistivity diffusivity measurements, compared neat polymers other blends.
