Abstract

A stable polytetrafluoroethylene superhydrophobic surface is prepared with filter paper which is first used as a template. Scanning electron microscope image shows a lotus-leaf like structure appears on the polytetrafluoroethylene surface. Altering the sintering temperature, the microstructure of the as-prepared surface also varied. After treating 12 h in acid, alkali or organic solvents, the as-prepared surface still retains superhydrophobicity and shows excellent stability.

摘要

以滤纸为模板制备了一种稳定的聚四氟乙烯超疏水表面。扫描电子显微镜图像显示聚四氟乙烯表面呈现出荷叶状结构。改变烧结温度，所制备表面的微观结构也会发生变化。在酸、碱或有机溶剂中处理12小时后，所制备的表面仍保持超疏水性并表现出优异的稳定性。
