【摘要】 采用阴极水平复合电沉积方式及先强烈搅拌5 min,然后通电开始复合电沉积的工艺,制备高复合含量的MWNTs-Ni复合电极.结果表明,当采用硫酸镍电解液、适当表面活性剂和光亮剂、电解液中ρ(MWNTs)=2 g/L且电流密度为2.5 A时,可获得w(MWNTs)=22.45%且结构致密的复合沉积层.其SEM照片显示MWNTs复合量已经达到最高极限,镍电结晶形态呈球形,结晶点位置多位于MWNTs管壁缺陷处及管端处,说明MWNTs复合电沉积为MWNTs基体与管端和管壁缺陷处结晶相互连接,形成牢固的复合沉积层.更多还原

【Abstract】 MWNTs-Ni electrode is prepared by stirring 5 min in cathode horizontal mode.The result shows compound MWNTs electrodeposit with 22.45% of content is prepared when sulfuric nickel electrolyte,surface active solvent and brightener are used and MWNTs=2 g/L,voltaic density=2.5 A.SEM shows MWNTs reaches highest content and sphericity,crystallization occurs on the sunk part and top of tub,which shows MWNTs compound electrodeposit is formed by connecting MWNTs matrix and crystals.更多还原
