Chitosan (CS), CS-poly(N-isopropylacrylamide)(PNIPAM) and their dyed (pyrene) hydrogels were prepared using glutaraldehyde (Glu) as a crosslinker. The gelation rate, swelling behaviors in ethanol/water mixtures, electricity-induced contraction and thermoresponse of the gels were investigated using f

## Abstract Amino semitelechelic poly(__N__โisopropylacrylamide) (PNIPAAm) was prepared by radical polymerization with aminoethanethiol hydrochloride as a chainโtransfer agent. Semiโinterpenetrating polymer network (semiโIPN) hydrogels, composed of alginate and amineโterminated PNIPAAm, were prepar
## SYNOPSIS The water state in crosslinked chitosan/polyether semi-IPN(cr-CS/PE semi-IPN) hydrogels swollen in buffer solutions with various pH values was studied using differential scanning calorimetry (DSC). The results show that the total water content and the amount of bound water is related t
