摘要： A new method capable of evaluating wettability of a surface of a material is provided.
The method includes the following: applying a gas jet to a surface of a material that is covered with a liquid so as to squeeze the liquid; imaging a surface of a liquid film formed on the surface of the material after squeezing the liquid; and evaluating wettability of the material based on the presence or absence of interference fringes on the surface of the liquid film.
