石墨烯/高密度聚乙烯导电复合材料的制备与表征
Preparation and characterization of Graphene Nanosheets/High Density Polyethylene Conductive Composites
摘要
Abstract
Graphene nanosheets (GNS) was prepared by chemical oxidation-reduction method. And Fourier transform infrared spec-troscopy (FTIR) , transmission electron microscopy (TEM) was used to characterize graphene oxide (GO) and GNS. GNS/high density polyethylene (HDPE) composite were prepared through solution mixing. The electrical properties of these composites were investigated. Percolation in GNS/HDPE composites occurs when the filler concentration is near 4. 3% (mass fraition, same below). The resistivity didn't change much when the weight fraction was above 6.5 (mass fraition, same below)%. DSC analysis reveals that the crystallization behavior of PE was significantly altered by addition of GNS, crystallization shifts to higher temperature during cooling, which indicates that GNS induces heterogeneous crystallization of PE.关键词
