Gradient innterpenetrating polymer networks. II. Polyacrylamide gradients in poly(ether urethane)

摘要

AbstractThe surface of poly(ether urethhane) is modified by preparing gradient interpenetrating polymer networks (IPNs) with polyyacrylamide hydrogels. Soveral experimental methods are used for preparing the gradient IPNs. Attenuated total reflection Fourier transform infrared (ATR‐FTIR) is used as the main characterization techniqu
