Stable polytetrafluoroethylene superhydrophobic surface with lotus-leaf structure
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
