Abstract
Poly (N-isopropylacrylamide)/poly(vinyl alcohol) (PNV) hydrogels were prepa red by repetitive freezing and thawing, This kind of hydrogels was formed t hrough physical crosslinking, i.e. hydrogen bonds during the freezing proce ss, The swelling ratio and deswelling/reswelling kinetics were measured gra vimetrically and this novel hydrogel exhibits a temperature-sensitivity. Th is hydrogel may be useful both in biomedical and biotechnological fields.
