Abstract :
A series of semi-interpenetrating polymer network (semi-IPN) materials were prepared by blending polymerization of acrylic acid (AA) in cationic starch (CS) and poly(methacryloyloxyethyl trimethylammonium chloride) (PDMC) solution. The crosslinker concentration, the feed ratio of the CS-g-AA to PDMC was discussed in term of the swelling capacity, and hydrogel properties were evaluated by network parameters Mc, morphological and compressive load tests. The semi-IPN hydrogels were also characterized by FT-IR spectroscopy to confirm the interactions between CS-g-AA and PDMC. Electron microscopy involved to staining of the anionic phases using CsF showed a transition from two-phase to compatible structure with the increasing content of PDMC, and further confirmed that the semi-IPN structure in hydrogels along with DSC. The resultant semi-IPN hydrogels were found to possess appreciable compatibility, good swellability and mechanical strength.
