摘要: 报道了近年来在电解加工技术制备理论密度金属薄膜和电沉积技术制备金属纳米丝阵列材料等领域取得的进展。采用硫酸＋甲醇电解液体系获得了表面粗糙度小于30 nm的钛膜。采用阳极氧化铝模板电沉积技术制备出长度约10 μm、直径约300 nm的金纳米丝阵列。主要讨论了电解液配方及电解加工参数的选择，金属纳米丝直径与长度的控制等问题。Abstract: Electrochemistry plays a very important role in inertial confinement fusion(ICF) target preparation. This paper reports the preparation of metal foil with theoretical density by electrical chemical machining and metal nanowire array by electrodeposition on anodized aluminum oxide(AAO) template. Ti foils with surface roughness less than 30 nm and Au nanowire arrays with length about 10 μm, diameter about 300 nm were prepared. The choices of electrolyte composition and electrochemical parameters, and diameter and length control of nanowires were investigated.
