A new type of organic–inorganic hybrid hydrogel (OIHH) was prepared under low air pressure using SiO2 nanoparticles as initiator. The obtained OIHH shows a novel microstructure and characteristics, which increased the salt resistance and water absorbance. We investigate the effects of the reaction conditions on the absorption ability. The xerogel shows absorbance of 339.9 and 102.8 g/g for distilled water and for 0.9 wt% NaCl solution. Moreover, a reasonable microstructure of the superabsorbent polymer is shown.
