Effects of Electroplating Parameters on Nano Carbon Growth by the Electrothermal Method CCVD

采用直热电热法研究不同电镀参数对碳纤维表面生长纳米碳形貌的影响,在不同电镀参数下对碳纤维表面进行电镀镍处理,然后将其进行化学气相沉积,从而得到实验所制备的纳米碳;比较在电镀参数不同前提下由沉积工艺得到纳米碳的大小、形状,解释电镀参数对该工艺制备得到的纳米碳的影响原因。结果表明,电镀时间为3 min条件下,碳纤维表面得到的镍催化剂颗粒分布比较均匀。电镀镍均匀分布在碳纤维表面,具有合适的尺寸大小,能更好的沉积出纳米碳,不同形状的镍催化剂颗粒能在碳纤维表面上沉积出不同形貌的纳米碳。

Direct heating electrothermal method was adopted to study the effects of different electroplating parameters on the morphology of nano carbon grown on the surface of carbon fibers.The nickel plating on the surface of carbon fiber was treated by electroplating with different electroplating parameters.Chemical vapor depo-sition of nickel plated carbon fibers prepared by electroplating was carried out to obtain nano carbon from experiments.Through technique of sedimentation,the sizes and shapes of the nano carbon with different electroplating parameters were compared in order to explore the relevant effects of electroplating parameters.The research results show that when the plating time is3min,the distribution of nickel catalyst particles on the surface of carbon fibers is uniform.The electroplating nickel is evenly distributed on the surface of carbon fiber,and it has a suitable size.The carbon fiber can produce better deposited carbon.Different shapes of nickel catalyst particles can grow on the surface of the fibers treated with different morphologies of nano carbon.
