Abstract: Poly( N-isopropylacrylamide)/poly(vinyl alcohol)(PNV) hydrogels were prepared by repetitive freezing and thawing. This kind of hydrogels was formed through physical crosslinking, i.e. hydrogen bonds during the freezing process. The swelling ratio and deswelling/reswelling kinetics were measured gravimetrically and this novel hydrogel exhibits a temperature-sensitivity. This hydrogel may be useful both in biomedical and biotechnological fields.

Key words: Temperature-sensitive, Freezing and thawing, Physical crosslinking, Hydrogel
