Abstract
A new poly(N-isopropylacrylamide) (PNIPA) hydrogel was prepared by decreasi ng the temperature of polymerization/crosslinking reaction below the freezi ng point (-18 degrees C). This PNIPA hydrogel shows a large swelling ratio at room temperature and exhibits a fast deswelling and reswelling rate in r esponse to external temperature changes. These properties are attributed to the macroporous and regularly arranged network of this PNIPA hydrogel.
