Characterization of Rough PTFE Surfaces by the Modified Wilhelmy Balance Technique

Characterization of Rough PTFE Surfaces by the Modified Wilhelmy Balance Technique

The wetting of rough polymer surfaces is of great importance for many technical applications. In this paper, we demonstrate the relationship between the mean roughness values and the fractal dimension of rough and self-affine PTFE surfaces. We have used white light interferometry measurements to obt...
