首先用Hummers法从石墨制得氧化石墨烯(GO),并用十六烷基三甲氧基硅烷(HTS)改性GO,然后将其化学还原得到功能化石墨烯(FG),X射线衍射和红外光谱分析表明,HTS已成功接到了石墨烯上;利用溶液共混法制备了聚乙烯醇缩丁醛(PVB)/FG纳米复合膜.用万能试验机、扫描电镜、电阻率测试仪、紫外-可见光透光率对材料进行了表征,结果表明,FG的质量分数为6.0％时,复合材料的拉伸强度可达到34.5 MPa,断裂伸长率达到44.5％;3.0％的FG就能让材料的导电率提高7个数量级;含FG 1.0％的复合膜(厚度为1 mm)对270～400 nm波长范围内紫外光的吸收率可以达到60％～80％.
