中文摘要：

碳纳米管（CNTs）表面化学镀是粉末冶金法制备CNTs增强金属基复合材料的重要预处理过程,也是提高其与金属基体界面结合强度的重要途径。本文通过微波辅助化学镀铜法制备CNTs-Cu复合粉体,并对该方法的反应速率和反应效果进行研究。通过碘量法测试镀液中Cu~（2＋）的浓度表征反应速率,XRD检测复合粉体中的物相组成,SEM和TEM分别观察复合粉体的微观形貌和结构。实验发现微波辅助化学镀的反应速率是常规化学镀方法的12倍,XRD和电子显微镜分析表明,微波辅助化学镀铜的效果良好,Cu颗粒还原较为充分,CNTs表面附着大量纳米铜颗粒,铜颗粒与CNTs结合紧密,且分布均匀。

英文摘要：

Carbon nanotubes （CNTs） surface chemical plating is one of the most important pretreatment processes for CNTs reinforced metal matrix composite prepared by the powder metallurgy method. It is likewise a useful way to improve the interface bonding strength of CNTs and metal matrix. In this paper, CNTs-Cu composite powder was prepared by microwave assisted method, the reaction rate and plating effects of the method were studied. The reaction rate was marked by iodine volume method for measuring the Cu2~ concentration, and the phase composition, morphology and structure of the composite powder were detected by XRD, SEM and TEM, respectively. It is important to emphasize that the reaction rate in microwave assisted chemical plating is 12 times higher than that in the conventional chemical plating method. XRD and electron microscope analysis suggest that the effect of microwave assisted chemical plating copper is just some of best, Cu particle is reduced more fully, and the surface of CNTs attaches a lot of Cu nanoparticles which are connected tightly and distributed evenly.
