I intended to correlate the structure of a biological membrane and that of the artificial membranes which had been employed widely in industrial fields. Two types of the membranes such as an ion-exchange membrane and an inactive membrane against ions were manufactured by the application of the common phenomena named as the micro-phase separation. This gave rise to the similar supermolecular structure for the resultant membranes : The former and latter ones were composed of the ion-cluster particles with ca. 5 nm in size and the primary particles with 10-15 nm, respectively. Although the affinity or chemical potential governed the formation of the structure of the membrane after the phase separation, the interfacial force working between the particles and the medium affected on the formation of the orientation of molecular chians at the surface. When we pay an attention to the similarity in the structure between both membranes of artificial and biological ones, the common driving forces for the formation of the membrane structure may be realized.
