Thermal-responsive hydrogels were fabricated by electrospinning of poly(N-isopropylacrylamide) (PNIPAM) based copolymer followed by UV-treatment. The fibrous structure maintained well morphologically after many swelling and de-swelling cycles. Higher than 10 times swelling rato achieved for hydrogels with all the crosslinker ratio and 50-60% remained for shrinking equilibrium hydrogles compared with swollen equilbrium. Both swelling and de-swelling equilbrum can be reached within very short time (4min) for sample with 1cm length and width and thickness of 0.1mm which is quiet large size compared to many micro-sized hydrogel samples.The higher ratio of crosslinker did not affect the swelling and de-swelling equilibrium ratio but leaded to the slower response rate.
