摘要: 　膨胀石墨经硼氧化物浸渍修后辊轧制成柔性石墨箔。应用激光质谱、X-光电子谱、扫描电镜和热重测定分析了所制柔性石墨箔。结果表明：浸渍硼氧化物后石墨箔的初始氧化温度提高了约150℃。即使浸渍少量（质量分数低于2%）的硼氧化物也能提高此材料的拉伸强度。纵观其浸渍改善效果，可能归因于膨胀石墨粒中与石墨片层化学键合的硼氧化物堵塞了其活性位点所致

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 2mass% 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.
