利用离子型表面活性剂( 十二烷基苯磺酸钠) 和非离子型表面活性剂( TX10 ) 对碳纳米管进行了预分散,不通过活化、敏化处理,直接采用化学镀方法在 CNTs 表面包覆金属铜。 对比了两种分散剂的分散效果,研究了镀液 pH 值、温度及施镀时间对包覆效果的影响。 结果表明:十二烷基苯磺酸钠的分散效果更好,更有利于镀铜;在镀液温度为 30 ℃ ,pH 为 11 ~ 12 的条件下施镀 30 min,可以获得被铜完全包覆的碳纳米管。

CNTs were pre-dispersed by ionic surfactants ( SDBS) and Non-ionic surfactants ( TX10 ) . Without activation and sensitization processing, copper was deposited directly on the surfaces of CNTs by electroless plating. Compared the effect of two dispersants, studied the affect of pH, temperature and time on coating effect . The results of the study show that the dispersing effect of SDBS is better and in the condition of 30 ℃ water bath, pH of 11 to 12 , electroless copper plating for 30 min, CNTs are coated completely by Cu.
