| 摘 要： | 利用偶联剂KH550对多壁碳纳米管(MWCNTs)进行化学修饰,并制备了MWCNTs/环氧树脂纳米复合材料.研究了不同含量的MWCNTs对纳米复合材料力学性能的影响.研究结果表明,MWCNTs表面成功接枝上了一定量的KH550,将其加入环氧树脂基体可大幅提高复合材料的力学性能.当添加量达到0.5%时,复合材料的力学性能最好,冲击韧度和弯曲强度较纯环氧树脂分别提高了85.3%和21.6%.扫描电镜结果显示,复合材料由脆性断裂转变为韧性断裂. |

| Abstract: | The multi-walled carbon nanotubes were modified with coupling agent KH550 and carbon nanotubes/epoxy resin nanocomposites were prepared.The effects of different MWCNTs contents on the mechanical properties of nanocomposites were studied.The results show that a certain amount of KH550 are introduced onto the surface of MWCNTs.The mechanical properties of nanocomposites are greatly enhanced by filling the proper amount of MWCNTs.When MWCNTs content is 0.5%,the mechanical properties are the best.Compared with ... |
