Abstract

In this study, the sodium allylsulfonate-starch based superabsorbent hydrogel (SAS-SBSH) with a uniform three-dimensional structure was prepared with gamma ray irradiation. SEM, FTIR and TGA characterized the microstructure, chemical composition and thermal properties of materials. SAS_5wt%-SBSH showed the highest water absorbency in water (951.17 g/g) and salt solution (30.92 g/g). SAS_3wt%-SBSH was the next best (709.57 g/g), having better repeated swelling performance than SAS_5wt%-SBSH. In addition, SAS_3wt%-SBSH showed high water absorbency in alkaline solution (pH = 9), which was 137.03 % of that in neutral solution. In summary, SAS-SBSH prepared in this study provided reference for the study of superabsorbent materials.

射线辐照法制备烯丙基磺酸钠淀粉基高吸水性凝胶及其性能研究

本研究采用伽马射线辐照法制备了具有均匀三维结构的烯丙基磺酸钠淀粉基高吸水水凝胶（SAS-SBSH）。SEM、FTIR和TGA对材料的微观结构、化学成分和热性能进行了表征。SAS5wt%-SBSH在水（951.17 g/g）和盐溶液（30.92 g/g）中的吸水率最高。其次是SAS3wt%-SBSH (709.57 g/g)，其重复膨胀性能优于SAS5wt%-SBSH。此外，SAS3wt%-SBSH在碱性溶液（pH = 9）中具有较高的吸水率，是中性溶液的137.03%。综上所述，本研究制备的SAS-SBSH为高吸水性材料的研究提供了参考。
