摘要:

提出一种金属铝超疏水表面的快速制作方法. 先以化学腐蚀在铝表面形成微米级粗糙结构, 再通过电化学腐蚀构筑纳米结构, 在20 min内完成了超疏水表面所需粗糙结构的制备. 这种化学腐蚀/电化学腐蚀两步法比单独化学或电化学腐蚀方法在时间上缩短了1~2个数量级, 且不受铝材晶形限制, 同时电化学腐蚀所用电流密度也降低了1个数量级, 降低了对电源设备的要求, 可望大规模应用于工业生产和其它金属的超疏水表面制备.

Abstract:

This paper presents a quick method for creating hierarchical micro/nano-structure on aluminum to achieve water-repellent surface. The method includes two steps i.e. chemical etching and electrochemical corrosion. SEM results show that the micro-structure can be easily obtained by means of chemical etching and nano-structure can be attained using electrochemical corrosion. And the micro/nano-sructure surface can be fabricated within 20 min by the two-step method. Compared to one-step electrochemical oxidization, this me-thod make the processing-time 1—2 order shorter and current density 1 order smaller. Meantime, it is una-ffected by the aluminum crystalline with respect to chemical etching. The two-step method is hopeful to be used in industry and expected to other metals for preparing super-hydrophobic surfaces.
