摘要

Temperature-responsive semi-interpenetrating polymer networks (semi-IPNs) constructed with chitosan and polyacrylonitrile (PAN) were crosslinked with glutaraldehyde. The semi-IPN determined the sorption behavior of water at several temperatures and at a relative humidity (RH) of 95% using a dynamic vapor sorption (DVS) system. Water diffusion coefficients of semi-IPNs were calculated according to the Fickian Law at several temperatures and exhibited a relatively water uptake, 0.1-0.4 at room temperature. The water uptake of hydrogels depended on temperature. The apparent activation energy was dependent of the composition of the semi-IPN with value of 32.8-34.8 kjmol(-1).
