PHOTORESPONSIVE AQUEOUS SOLUTION AND ITS USE

摘要

PROBLEM TO BE SOLVED: To provide a technique whereby the viscoelastic behavior of an aqueous solution containing stringy micelle structures can be easily and reversibly controlled. SOLUTION: The purpose is attained by using a photoresponsive aqueous solution which contains a quaternary ammonium salt, a micelle formation inductive substance, and a quaternary ammonium salt of an azobenzene compound.
