The physical property of epoxy/graphene nanoplatelets composites prepared by ball milling

Abstract

Abstract. Epoxy/graphene nanoplatelets(EP/GNs) composite was prepared by ball milling(BM), using diglycidyl ether of bisphenol A(DGEBA)as matrix, Diethyltoluene diamine(DETDA) as curing agent, GNs as thermal conductive filler. The mechanisms and influence of different BM time to exfoliate layered GNs and compound with Epoxy resin were investigated. The morphology, thermal conductivity of EP/GNs composite were investigated too. It showed that BM was an effective method to prepare EP/GNs conductive composite of low loading level by avoiding aggregation of GNs.
