摘要: 为解决碳纳米管在铜基体中的分散与结合两个问题, 运用超声振荡辅助复合电镀制备铜基碳纳米管(Cu/ CNTs) 复合镀层。利用场发射扫描电镜进行观察, 复合镀层微观表面平整, 碳纳米管在基体中均匀分散, 其与基体结合良好。依据实验结果对超声振荡在复合电镀过程中发挥作用的机制给出了初步的解释。Abstract: In order to disperse the carbon nanotubes (CNTs) equably in the composite and develop the interconnection between CNTs and the copper mat rix , composite elect roplating with the aid of ult rasonic agitation was employed to prepare the copper/ CNTs composite coatings. SEM was used to observe their morphology. It was verifiedthat the surface of the composite is quite smooth ; CNTs are equably dispersed throughout the mat rix , and in addition , the interfacial binding between CNTs and copper was well. In these cases , a brief understanding of the effectof the ult rasonic agitation on the codeposition was ascertained.
