The Effect of Polymerization Mode on the POSS Hybrid PVA Hydrogels

Article Preview

Abstract:

A novel POSS hybrid nanocomposite hydrogels was synthesized by introducing water-soluble Oa-POSS into the PVA hydrogels by freeze-draw mode. The freezing temperature and freeze-thaw cycle times affected the mechanical properties of gels. When polymerizing at lower temperature, the tensile strength and modulus increases and the elongation at break decreases obviously. Meantime, with the increase of freeze-thaw cycle times, the strength, modulus and elongation at break all improved gradually.
