摘要：

To test the effects of vapour adsorption on contact angle measurements, contact angles of high-vapour-pressure liquids and low-vapour-pressure liquids on a hydrophobic solid surface (FC721) were measured by using the axisymmetric drop shape analysis-profile (ADSA-P) technique. Details of the surface preparation and the experiments are presented. By plotting the experimental data in terms of gamma(lv) cos theta vs. gamma(lv), this study shows that the vapour adsorption on a fluorocarbon surface, FC721, is negligible.
