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
โฅ-Ray radiation on poly(glucosyloxyethyl methacrylate) [poly(GEMA)] and poly(glucosyloxyethyl acrylate) [poly(GEA)] aqueous solutions without any crosslinkers gives glycoside-bearing hydrogels in a high yield. The degree of the swelling ratios of each obtained hydrogel in water was decreased with an
