METHOD FOR EVALUATING WETTABILITY OF SOLID SURFACES

WIPO Patent Application WO/2024/053598

A1

Provided is a method that makes it possible to more easily and quantitatively obtain the surface wettability of a solid with respect to a discretionary liquid.　The present invention is a method for evaluating the wettability of solid surfaces in which surfaces to be evaluated in two solids are made to face each other with a space therebetween, at least all of the bottom edge sections of the two solids are arranged so as to be present on the same plane and the result is used as a test material, an immersion test is performed in which the test material is immersed in an evaluation liquid so that all of the bottom edge section of the test material is parallel to the surface of the evaluation liquid, a wetting height which is the difference between the height of the surface of the evaluation liquid and the height of the liquid surface of the evaluation liquid entering into a gap between the two solids is measured at a discretionary immersion time, and the measured value is designated as a wettability evaluation value for the solid surfaces with respect to the evaluation liquid.
