Fabrication of Multiwall Carbon Nanotube-nanocrystalline Copper Nanocomposite Film by Electrochemical Deposition

摘要

A new method of fabricating nanocomposite films made up of multiwall carbon nanotube and nanocrystalline copper was developed by using an electrochemical deposition. The electroplated CNT/Cu nanocomposites have the microstructure that CNTs are well dispersed in both the planar and depth directions without any voids in the matrix. The conditions were successfully achieved by using some amphiphilic polymers, organic additives and a pulse electrodeposition method. The microstructure and CNT composition of nanocomposite films were strongly affected by the concentration of CNT in the electrolyte. The mechanical and electrical properties of CNT/Cu nanocomposite films were investigated with the variation of CNT content in the nanocomposite films.
