1、第43卷第2期塑料工业CHINAPLAS【CSINDUSTRY·63·2015年2月超声辅助原位聚合聚吡咯/石墨烯纳米复合材料的制备及其性能研究水黄方麟,章健,柯星宇,范萍。,曹征,钟明强(1.浙江工业大学材料科学与工程学院,浙江杭州310014;2.浙江省地质矿产研究所,浙江杭州310007)摘要:利用超声波的分散、粉碎、活化、引发等多重作用以及吡咯单体与石墨烯的一相互作用,在实现石墨烯均匀分散的同时,使吡咯单体在石墨烯表面进行原位聚合反应,制备出聚吡咯/石墨烯(PPy/RGO)纳米复合材料。运用扫描电子显微镜(SEM)、红外光谱(FTIR)、X射线光电子能谱(XPS)等测试
2、手段对PPy/RGO纳米复合材料的表面特性、化学组成及结构等进行了表征。在此基础上,研究了制备过程中的各种因素(如氧化剂、反应温度、石墨烯含量等)对PPy/RGO纳米复合材料产率及导电性能的影响。并采用热重分析(TGA)和导电测试分析了石墨烯含量对其热稳定性及电导率的影响。关键词:复合材料;聚吡咯;石墨烯;超声;原位聚合DOI:10.3969/j.issn.1005-5770.2015.02.015中图分类号:TQ320.9文献标识码:A文章编号:1005—5770(2015)02—0063—06StudyonPolypyrrole/GrapheneNanocompositeP
