ABSTRACT:
A method for treating the surface of a solid to impart a desired degree of roughness by forming a large number of tiny indented points is disclosed. First, a large number of tiny liquid droplets is dispersed all over the surface of the solid. Then, a layer of a diluted solution of plastic dissolved in a volatile solvent is formed on the surface, covering the droplets. After the volatile solvent has evaporated, a plastic film containing a large number of tiny holes is formed on the surface of the solid. Etching is then done on the surface using the said plastic film as a mask, thus, a large number of tiny indented points are formed on the surface of the solid.
