Novel pH-responsive hydrogels based on chemically modified Arabic Gum polysaccharide

摘要

AG-MA was obtained by reaction with glycidyl methacrylate in an appropriated solvent mixture. The cross-linking reaction of AG-MA forms AG-MA hydrogels that showed significant pH dependence, which had considerable effect on the water absorption transport mechanism. In the pH range studied, it was found that the water uptake mechanism of the AG-MA hydrogel was controlled by polymer relaxation (anomalous transport). The AG-MA hydrogels exhibited pH-responsive, which makes them a potential polymeric drug carrier.
