PROBLEM TO BE SOLVED: To provide a technology for optically controlling whether or not a liquid in one face of a porous film having fine pores of a nanometer size penetrates/permeates or not.SOLUTION: A liquid separation method characterized in that a liquid is passed as a vapor through pores by applying either a liquid or a solution, in which a nonvolatile substance is dissolved, onto a porous film material having reversible optical isomerization radicals in pores, and by optically irradiating said film material. |
