| 摘 要： | 通过共价键修饰将酸化的多壁碳纳米管(MWNTs)与环氧树脂进行接枝反应,并通过傅立叶变换红外光谱(FTIR)、X射线衍射(XRD),拉曼光谱(Raman spectra),热失重分析(TGA)和透射电镜(TEM)对其进行表征.研究发现,酸化处理在多壁碳纳米管管壁产生羧基、羟基,并检测到环氧树脂是通过共价键接枝到多壁碳纳米管管壁上,其接枝率达到39%.差示扫描晕热仪(DSC)显示改性的多壁碳纳米管对环氧树脂的固化反应有显著的影响.

| Abstract: | Epoxy resin was grafted on the acidified Multi-carbon nanotubes(MWNTs) by covalent modification method.The changes in chemical and physical structure were investigated by FTIR,Raman spectra,TGA and TEM.As a result,when MWNTs were modified with strong acid,the carboxyl and hydroxyl groups were found on the surface of MWNTs.The epoxy groups had covalently grafted onto the surface of MWNTs and epoxy resin content on MWNTs surface was about 39%.The curing behaviors of MWNTs/epoxy nanocomposites were examined by... |
