采用高能量超声波与低能量超声波对一种多壁碳纳米管(MWCNTs)/环氧树脂体系进行改性处理,结合流变仪、DSC、FTIR、XPS、XRD、TEM等测试手段,分析了不同超声波处理条件下MWCNTs物理化学特性的变化及其对MWCNTs在环氧树脂中的分散性和相容性的影响,并进一步考察了MWCNTs/环氧树脂体系的耐热性和弯曲性能.实验结果表明:超声波能量不同,MWCNTs的改性效果不同,高能量超声波对MWCNTs有更好的分散效果和分散效率,并能使MWCNTs表面活性增强,而低能量超声波则不明显;添加少量高能量超声波改性的MWCNTs,可以提高环氧树脂的弯曲模量和玻璃化转变温度,表明MWCNTs与基体之间形成了较强的结合界面.
