采用化学镀法在多壁碳纳米管表面沉积钴-铁涂层。主要研究了镀液中钴盐和铁盐的摩尔比、络合剂浓度和镀液温度对镀层的影响。在钴-铁的摩尔比为9∶1,络合剂浓度为0.32mol/L,镀液温度为60℃时,可得到的较为平整的镀层,且镀层中钴-铁摩尔之和达90%以上。其他条件下,则会在镀层中出现金属颗粒或钴-铁含量过少的情况。 Electroless plating was used to deposit cobalt-iron coating on the surface of multi-walled carbon nanotubes. The main study of the cobalt bath salt and iron salt molar ratio, complexing agent concentration and bath temperature on the coating. In the cobalt-iron molar ratio of 9: 1, the complexing agent concentration of 0.32mol / L, the bath temperature is 60 ℃, the relatively flat coating can be obtained, and the coating cobalt-iron molar sum of 90% the above. Under other conditions, there will be metal particles or cobalt-iron content is too small in the coating.
