英文摘要	Intelligent hydrogel was a kind of crosslinked polymer which can response to external stimuli such as temperature, pH values, light, electricity and ionic strength. These pH sensitive gel ball can be used in the biological medicine, environmental protection and other fields. The authors mainly studied the swelling and deswelling performance of SPM hydrogel microspheres made from sodium alginate (SA), polyvinyl alcohol (PVA) and montmorillonite (MMT). The sensitivity to the pH values, salinity and temperature was also tested. The experimental results show that the SA concentration was positively correlated with swelling performance while MMT had the negatively effect. The content of carbonyl groups and other groups in alkane chains reduced and the possible chemical reaction can occur. These gel balls are sensitive to alkaline environment and high salt concentration, but not sensitive to temperature. © 2015, Journal of Functional Materials. All right reserved.
