摘　　要：采用超高速剪切法制备了未改性多壁碳纳米管(MWCNTs)/硅橡胶复合材料、羟基化MWCNTs/硅橡胶复合材料和羧基化MWCNTs/硅橡胶复合材料,通过傅里叶变换红外光谱仪、多功能表面分析电子能谱仪和动态力学分析研究了复合材料的界面作用。结果表明,羧基化MWCNTs/硅橡胶复合材料的界面作用最强,羟基化MWCNTs/硅橡胶复合材料其次,未改性MWCNTs/硅橡胶复合材料最弱。The pure multiwalled carbon nanotubes（MWCNTs）/silicone rubber composite,hydroxylated MWCNTs/silicone rubber composite and carboxylated MWCNTs/silicone rubber composite were prepared by means of high speed homogenizer,and the interfacial interaction of the three kinds of composites were studied by Fourier transform infrared spectroscopy,X-ray photoelectron spectroscopy and dynamic mechanical analysis.The results proved that the interfacial interaction of carboxylated MWCNTs/silicone rubber composite achieved the most intensive,while that of pure MWCNTs/silicone rubber the weakest.
