摘要
制备了一种新型的耐酸碱性的水相超疏油铜表面.在水相中,油滴在其表面上的接触角高达162°,同时极易滚动,表明所得到的表面不但具有水相超疏油特性,同时还表现出较低的黏附性及较强的耐酸碱能力.在不同pH值(2—12)的水溶液中,这种低黏附超疏油特性依然存在.研究表明,该表面的水下超疏油及低黏附特性主要源于表面亲水性的化学组成及独特的微纳米等级结构之间的协同作用.而较强的耐酸碱性则得益于铜材料自身较好的化学稳定性.
A novel superoleophobic copper surface in water with special acid/basic resistant property was re- ported. When the surface is placed under water, an oil droplet has a high contact angle of about 162°, indica- ting that the surface is superoleophobic in water. Meanwhile, the surface is low adhesive to the oil droplet, and an oil droplet can roll on the surface easily with a sliding angle of about 3 ~. Noticeably, the surface has a special acid/basic-resistant property and can retain the low adhesive superoleophobic performance at various pH values(2--12) in water. The low adhesive superoleophobic property in water can be ascribed to the com- bined effect of the hydrophilicity and the hierarchical structures on the surface, and the acid/basic-resis-tance is due to the chemical stability of copper substrate.
