Thermo-responsive polymer gel and heat -responsive polymer gel film .

摘要

PROBLEM TO BE SOLVED: To provide a thermoresponsive polymer gel which changes a degree of swelling at a large speed or largely changes the water drop contact angle of the gel surface, by thermal stimulation, and to provide a thermoresponsive polymer gel film.;SOLUTION: There are provided the thermoresponsive polymer gel whose mass is reduced from the maximum water-containing state to ≤20% of the maximum water-containing state by thermal stimulation within 300 sec, or whose surface water drop contact angle difference between before and after the thermal stimulation is ≥20°, and the thermoresponsive polymer gel film is formed from the thermoresponsive polymer gel in a film-like shape.;COPYRIGHT: (C)2010,JPO&INPIT
