摘要:

采用3-氨基丙基三乙氧基硅烷偶联剂(KH550)对氧化石墨烯表面进行修饰, 得到功能化氧化石墨烯(FGO), 然后在引发剂偶氮二异丁腈(AIBN)作用下, 以甲基丙烯酸丁酯(BMA)为单体进行原位聚合反应, 得到功能化氧化石墨烯/聚甲基丙烯酸丁酯 (FGO/PBMA)复合材料. 通过红外光谱(FTIR)、 X射线光电子能谱(XPS)、 扫描电子显微镜(SEM)和热重分析(TGA)等手段对复合材料进行表征. 结果表明, 所制备的FGO/PBMA复合材料与聚甲基丙烯酸丁酯材料相比热稳定性显著提高, TGA结果显示, FGO/PBMA的最大失重区由PBMA的267 ℃升高到339 ℃, 同时对反应机理进行了探讨.

Abstract:

Graphene oxide(GO) nanosheets was modified by 3-triethoxysilylpropylamine(KH550) to get functional graphene oxide(FGO). Then FGO was reacted with butyl methacrylate(BMA) via in situ polymerization with the initiator AIBN in N2. The prepared functional graphene oxide/polybutylmethacrylate(FGO/PBMA) composites were characterized by Fourier transform infrared spectroscopy(FTIR), X-ray photoelectron spectrometry(XPS), scanning electron microscope(SEM) and thermal gravimetric analysis(TGA). The thermal stability of the FGO/PBMA composites were significantly enhanced compared with that of neat PBMA. The maximum mass loss temperature increased from 267 ℃ for neat PBMA to 339 ℃ for FGO/PBMA composites. Meanwhile the reaction mechanism was also discussed.
