摘要：

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. (c) 2009 Elsevier Inc. All rights reserved.
