Fundamental research on novel surface analysis method with condensed liquid drops

Abstract

In order to evaluate surface properties as wettability and surface energy, novel surface analysis method was proposed with the observation of condensed liquid drops on the specimen in an ESEM. In the present study, indentations were made on a soda-lime glass plate with a sharp knife-edge of diamond, and the condensation of water on the glass plate as liquid drops were observed. As a result, the condensation of water was started from indentations marked on glass plate and spread to the other area. On the basis of adsorption mechanism, capillary condensation to the cracks in indentation has an important role for selective condensation to the glass.
