Xz. Zhang et Rx. Zhuo, Novel synthesis of temperature-sensitive poly(N-isopropylacrylamide) hydrogel with fast deswelling rate, EUR POLYM J, 36(3), 2000, pp. 643-645
Poly(N-isopropylacrylamide) (PNIPA) is a thermosensitive hydrogel and under
goes volume changes in response to external temperature changes. In some po
tential applications of PNIPA hydrogel, a fast response rate is needed. Her
l, a novel PNIPA hydrogel was synthesized by using water/actone (v/v, 1:1)
as mixed solvent during the redox polymerization/crosslinking reaction. The
characterization of this PNIPA hydrogel was gravimetrically measured, and
it exhibits much faster deswelling rate than that of the normal-type PNIPA
hydrogel. (C) 2000 Elsevier Science Ltd. All rights reserved.
