摘　　要：采用重氮盐法对多壁碳纳米管(MWNT)进行磺化改性,增强碳纳米管在水中的分散性,然后以水为溶剂,以溶液共混法制备高分散性的碳纳米管/聚乙烯醇(MWNT/PVA)纳米复合材料,用红外(FTIR)、扫描电镜(SEM)、热重(TGA)等手段对复合材料的微观结构和性能进行表征和分析.结果表明:该方法可以将碳纳米管均匀地分散在聚乙烯醇(PVA)基体材料中,形成高分散性的碳纳米管/聚乙烯醇纳米复合材料,并且在碳纳米管含量较低的情况下就可以有效地增强聚乙烯醇的耐热性能.The Sulfonated MWNTs were prepared via aryl diazonium salts method to improve the disper-sity of MWNTs.The Sulfonated MWNTs/ polyvinyl alcohol(MWNT/PVA) nanocomposites were preparedsuccessfully by solution-mixing method using water as solution.The microstructure and property of Sulfo-nated MWNTs/PVA nanocomposites were investigated by FTIR,SEM and TGA.The results showed thatthe functionalized CNTs could be homogeneously dispersed into the PVA matrix by this method.Thethermal properties of PVA were remarkably improved at low loading of the Sulfonated MWNTs.
