| 摘 要： | 采用熔融混合法向低粘度的环氧树脂中添加适量的多壁碳纳米管,制备新型纳米复合材料,并采用傅里叶变换红外光谱仪(FT-IR)测试转化率,采用差示扫描量热法(DSC)研究多壁碳纳米管/环氧树脂复合体系的固化动力学,并对纳米复合材料的力学性能进行研究。结果表明:多壁碳纳米管加入环氧树脂复合体系后,对固化反应有催化作用,固化反应速率增大,转化率提高,而复合体系的力学性能却有所下降,玻璃化转变温度变化不大。

| Abstract: | MWNTs/epoxy nanocomposites were prepared with different content carbon nanotubes and epoxy resin through melt methods.Fourier transform infrared spectrum(FT-IR)was employed to test the conversion rate of the nanocomposites.The curing behaviors of MWNTs/epoxy nanocomposites had been studied by differential scanning calorimetry(DSC) technique.As a result,with MWNTs incorporated into the epoxy resin curing system,the cure rate and conversion rate were increased,but mechanical properties of nanocomposites decreased and glass transition temperature had no obviously change. |
