The Swelling Behavior of Water-Soluble POSS Hybrid PNIPA Nanocomposite Hydrogels

Abstract:

The nanosized water-soluble Oa-POSS particles were added into the PNIPA hydrogels by in situ radical polymerization as a reinforce agent. The swelling behavior including swelling ratio and swelling/deswelling rate was determined by the composition of gels. With the increase of Oa-POSS, the swelling ratio decreases slightly, while the swelling rate and deswelling rate increases significantly, which is conducive to the application of this kind of gels.
