Abstract
Monodispersed latex particles in aqueous solutions were deposited on a semipermeable membrane through which electrolytes permeated, and it was found that a two-dimensional ordered structure of these particles was formed under a certain condition. The mechanism of ordering was studied qualitatively using the DLVO theory, and the formation of an ordered structure was found to be closely related to the existence of the secondary minimum of the potential between the substrate surface and the particles.
