摘    要:为改善尼龙 6 (PA6 )的力学性能 ,加入碳 nm管(CNTs)与之复合 ,制作 CNTs/ PA6复合材料 ,以提高基体PA6的力学性能 ,特别是抗拉强度。通过采用原位法复合CNTs与 PA6 ,获得了由 OC C化学键连接的、理想的CNTs/ PA6界面的、且 CNTs在基体 PA6中分散均匀的CNTs/ PA6复合材料 ,其抗拉强度有较大幅度的提高 ,同时还保持较高的冲击韧性和延伸率。经检测 ,CNTs/ PA6复合材料的断裂界面不象其它纤维增强 PA6复合材料那样在纤维 / PA6界面上 ,而是在 PA6包裹层与 PA6基体界面上。研究结果表明 ,采用原位复合法 ,CNTs能够对 PA6基体起到很好的增强作用

关 键 词:碳nm管  尼龙-6  复合材料  原位复合

Abstract:Mechanical properties of nylon 6(PA6) were improved by making a composite carbon nanotubes(CNTs) with PA6. An in situ process was used to fabricat CNTs/PA6 composites that have a strong CNTs/PA6 interface linked by C O C chemical bonds between the CNTs and the matrix with a homogeneous distribution of CNTs in the PA6 matrix. The composites have a higher tensile strength with good toughness and elongation. Experimental results show that the fracture interface is not at the CNTs/PA6 interface as with other fiber reinforced polymer composites, but at the interface between the PA6 layer wrapping the CNTs and the PA6 matrix. The research results show that CNTs can reinforce the PA6 matrix.
Keywords:carbon  nanotubes  nylon-6  composites  in situ process
