## Abstract A novel acrylamide/maleic acid copolymer [P(AMβMA)] hydrogel nanofibrous membrane with a fiber diameter of ca. 120 nm is prepared by electrospinning an aqueous P(AMβMA) solution with diethylene glycol as crosslinker, followed by a heatβinduced esterification crosslinking reaction at 145
A novel polypeptide hydrogel has been synthesized by crosslinking poly(L-glutamic acid) (PLG) with poly(ethylene glycol) (PEG). The PLG-PEG hydrogel was shown to be highly hydrophilic, and the extent of swelling varied with pH, increasing at higher ionization of the PLG. Aside from electrostatic eff
