摘要Abstract: SiO2-polyacrylic acid hybrid hydrogel was synthesized using sodium silicate (SS) as precursor through sol–gel technology. The result showed a core–shell structure was formed with SiO2 inner core and acrylic acid (AA)outer shell. The characteristics of the hydrogel were determined by FTIR and TEM. When the mol ratio of SS/AA was 0.13, the compressive strength of the hydrogel reached 45.6 kPa at 99.1% water content while the swelling ratio was 1017.2 g/g in deionized water. Moreover, a high salt tolerance was also obtained.
