Poly[N-isopropylacrylamide-co-(maleic acid)], poly(NIPA-co-MA), was synthesized by radical polymerization in an aqueous solution composing of 35% molN-isopropylacrylamide/maleic acid. Poly(NIPA-co-MA) hydrogel nanofibrous membrane was fabricated by electrospinning using ethanol as solvent. The electrospun nanofibers were cross-linked using diethylene glycol as cross-linker, followed by a heat-induced esterification reaction at 145°C. The average diameter of electrospun fibers was 117 ± 33 nm. The hydrogel membrane exhibited a temperature sensitive property. Its minimum and maximum water absorption ratios were 4 ± 0 g g−1at 50°C and 17 ± 4 g g−1at 34°C, respectively. An equilibrium swelling state of the electrospun membrane was reached within 5 min.
