超疏水金属表面引起了广泛的兴趣。在这项工作中，开发了两种简便的一步法（置换反应和电沉积）来制造具有分层多孔树枝状结构的超疏水Bi/Bi2O3表面，其中Bi2O3覆盖层是通过沉积Bi的表面自钝化形成的。详细研究了各种实验参数对表面形貌和润湿性的影响，包括溶液浓度、沉积时间和沉积电位。通过这两种方法在优化条件下无需额外的表面修饰即可在制备的超疏水Bi/Bi2O3表面上获得约164度的最大接触角。 (C) 2013 Elsevier B.V. 保留所有权利。
Superhydrophobic metallic surfaces are attracting wide interest. In this work, two facile one-step methods (displacement reaction and electrodeposition) were developed to fabricate superhydrophobic Bi/Bi2O3 surfaces with hierarchical porous dendritic structures, where the Bi2O3 cover layer was formed by surface self-passivation of the deposited Bi. The influence of various experimental parameters on the surface morphology and wettability were investigated in detail, including concentration of solutions, deposition times, and deposition potentials. A maximum contact angle about 164 degrees can be obtained on the fabricated superhydrophobic Bi/Bi2O3 surfaces by these two methods under optimized conditions without additional surface modification.
