Abstract

We describe a simple and inexpensive method to produce super-hydrophobic surfaces on aluminum and its alloy by oxidation and chemical modification. Water or aqueous solutions (pH = 1-14) have contact angles of 168 +/- 2 and 161 +/- 2 degrees on the treated surfaces of Al and Al alloy, respectively. The super-hydrophobic surfaces are produced by the cooperation of binary structures at micro- and nanometer scales, thus reducing the energies of the surfaces. Such super-hydrophobic properties will greatly extend the applications of aluminum and its alloy as lubricating materials.

摘要

我们描述了一种通过氧化和化学改性在铝及其合金上制备超疏水表面的简单且低成本的方法。水或水溶液（pH = 1 - 14）在铝和铝合金的处理表面上的接触角分别为168±2度和161±2度。超疏水表面是由微米和纳米尺度的二元结构协同作用产生的，从而降低了表面能。这种超疏水性能将极大地扩展铝及其合金作为润滑材料的应用。
