石墨烯包覆玻璃纤维复合材料的制备及其电学性能研究
Preparation and Electrical Properties of Graphene Coated Glass Fiber Composites
摘要
Abstract
The graphene coated glass fiber composites were obtained from the electrostatic adsorption of graphene oxide on bovine serum albumin (BSA) modified the glass fibers, and the subsequent reduction of graphene oxide coated glass fibers by hydroiodic acid at low temperature of 40℃. The phase structure and functional groups of gra-phene oxide were studied by XRD and FT-IR, respectively. SEM images showed that the graphene wrapped effect was improved with pH decreasing, when pH of graphene oxide dispersion was less than 6. Zeta potential of graphene oxide and BSA molecule were tested by Particle size/Zeta potential instrument, which showed that the isoelectric points of graphene oxide and BSA were smaller than 3 and 5.3, respectively. Conductivity of graphene wrapped glass fiber composites reached 4.5 S/m, and conductive glass fibers maintained original conductivity after different levels of bending. Moreover, due to the reduction of graphene, the conductivity increased slightly after the heat-treatment above 100℃. These results prove that the conductive glass fibers can be used at high temperature.关键词
