| 摘 要： | 碳纳米管性质奇特、用途广泛1]。目前制备碳纳米管薄膜的方法主要有电弧放电法2]、催化裂解3]、及真空过滤碳纳米管悬浮液制备“巴基管纸”(Buckypaper)4]等。本文采用镀镍基板催化裂解低碳烷烃法制备碳纳米管薄膜,考察了镀膜时间、蚀刻和氨水处理等条件对碳纳米管薄膜产物形貌的影响。1 实验部份1 1 镀膜与后处理采用离子溅射法在硅酸盐基板上镀镍,镀镍电流7 5mA,镀镍时间分别为2min、15min、30min、45min或60min;对镀镍基板再进行蚀刻(蚀刻电流7 5mA,蚀刻时间2min)或用氨水浸泡处理(含NH325%,超声振荡30min),然后烘干备用。1 …

| Abstract: | Silicate substrates were coated by ion sputtering with nickel,and then used to catalyze the decomposition of low hydrocarbons to prepare the relatively well distributed carbon nanotubes films(CNFs).The effects of sputtering time,etching,and treatment in ammonia water on the morphology of CNFs were investigated,respectively.SEM measurements showed that the morphology of CNFs became more orderly with the increase of sputtering time,and carbon nanotubes of CNFs would not arrange very tightly after the coated nickel films were etched or/and treated in ammonia water for some time. |
