摘要
Abstract
Flexible graphite foil produced by rolling expanded graphite impregnated with boron oxide was analyzed by laser mass spectroscopy,X-ray photoelectron spectroscopy,scanning electron microscopy and thermogravimetry.It was shown that the modification of the graphite foil by boron oxide increases the onset temperature of oxidation by ～ 150 ℃.Impregnation of less than 2 mass％ boron oxide also increased the tensile strength of the materials.The observed improvement was attributed to the blocking of active sites by boron oxide,which is probably chemically bonded to the edges of graphene sheets in expanded graphite particles.关键词
