Carbon nanotube films grown on nickel sheet by CVD method were directly used for the electrode materials of capacitive deionization device(CDD). The surface structures of carbon nanotube films were characterized by FESEM,TEM and BET.

• 采用低压CVD法制备得到的金属镍基碳纳米管薄膜直接作为电容去离子器(CDD)的电极材料,并对碳纳米管薄膜进行了扫描电镜观察和比表面与孔径分析,探讨了该电极材料的电容吸附性能。
