疏水植物表面微纳复合结构电铸模芯的制备

摘要

以竹叶下表面为疏水生物母板,针对疏水表面电铸成型的特殊性,分别采取湿润剂浸润处理和阴极水平旋转运动两个技术手段改善微纳复合结构的电铸成型质量.结果表明:浸润处理可有效提高沉积离子在微纳米凹槽内部的沉积,阴极水平旋转对提高电铸镍模芯宏观质量和微观结构复制质量均有一定效果.采用浸润处理与阴极旋转相结合的电铸复制工艺,可明显提高竹叶下表面微纳复合结构的复制质量,成功实现具有疏水植物表面微纳复合结构的模塑成型镍模芯的高质量制备.%The lower surface of bamboo leaves was adopted as a hydrophobic surface master .Regard-ing the characteristics of electroforming for hydrophobic surfaces ,a wet-out treatment and a cathode horizontal-rotation were adopted to improve the replication quality of micro-nano hierarchical struc-tures .The results show that the wet-out treatment can effectively improve the nickel ion deposition in the micro-nano cavities .The cathode horizontal-rotation is proved to be helpful for the better macro-and micro-qualities of electroformed nickel mold inserts .Electroforming technology with the wet-out treatment and the cathode horizontal-rotation can significantly improve the replication quality of micro-nano hierarchical structures of bamboo leaf surfaces ,and can be used to successfully fabricate the hy-drophobic nickel mold inserts with high quality for further molding.
