通过复合电沉积技术制备了锌基碳纳米管复合薄膜.其中,碳纳米管表面的锌沉积层平滑连续,无明显界面缺陷,与其它金属基碳纳米管复合材料相比,这种独特的界面形貌是值得注意的.在对材料变形区的观察中发现,在薄膜变形的过程中,适中的结合强度将允许碳纳米管与基体发生界面脱黏,碳纳米管被拔出基体后桥联在裂纹中.虽然界面结合受到损伤,但是仍然可以有效地传递应力.当裂纹继续扩展,碳纳米管石墨片层开裂,直至完全断裂.同时,这些桥连在裂纹中的碳纳米管趋向于向垂直于裂纹的方向滑移,它们在基体中移动时会对基体造成一定程度的损伤.这些过程都将消耗大量的破断能,从而起到对基体的增强效果.锌基碳纳米管复合薄膜的平均硬度由HV178.3上升至HV493.5.
