METHOD FOR FORMING PARTICLE LAYER ON SUBSTRATE, METHOD FOR FLATTENING IRREGULAR SUBSTRATE SURFACE, AND PARTICLE-LAYERED SUBSTRATE

摘要

A method for forming a particle layer on a substrate comprising the steps of: developing a dispersion liquid (I) obtained by dispersing in a dispersion medium solid particles surface-treated with a compound capable of forming a binder, on a liquid (II) incompatible with the dispersion medium; removing the dispersion medium from the dispersion liquid (I) to form a particle layer in which the solid particles are arranged; and transferring the particle layer onto a substrate. The method provides a substrate with a particle layer having a high adhesion to the substrate. A method for flattening an irregular substrate surface comprises the steps of: transferring the particle layer formed by the first method to an irregular surface of a substrate; and removing portions of the particle layer formed on protuberances of the substrate. A particle-layered substrate comprises a particle layer obtained by the above methods on the substrate.
