摘要：

The effect of roughness on wettability of skived PTFE and Na-treated PTFE film were studied by advancing contact angle measurements. The effect of an anisotropic force field of elongated Na-treated PTFE on the shear bond strength were also studied as a function of elongation. The results are analyzed in terms of London dispersion gamma s**d and Keesom polar gamma s**p contributions to surface energy gamma s. It was found that the roughness effect on wettability of PTFE is significant for untreated PTFE and negligible for Na-treated PTFE.
