制备了四脚状氧化锌 (T ZnO)晶须增强尼龙 6复合材料 ,详尽地研究了晶须的表面处理、晶须增强尼龙 6复合材料的力学性能、耐热性及尺寸稳定性 ,并用扫描电镜对复合材料的拉伸断口进行了观察。研究表明 :用KH 5 5 0作为该体系的偶联剂 ,其加入量以 0 5 %为宜 ;T ZnO晶须的加入可提高尼龙的拉伸强度 ,增加尺寸稳定性及耐热性。 The preparation of tetrapod-like ZnO (T ZnO) whiskers reinforced nylon 6 composites, the surface treatment of whiskers, the mechanical properties, heat resistance and dimensional stability of whisker reinforced nylon 6 composites were studied in detail. Electron microscopy tensile fracture of the composite was observed. The results show that: KH550 as the coupling agent, the amount of 0-5% is appropriate; T ZnO whiskers can increase the nylon tensile strength, increase the dimensional stability and heat resistance.
