The Effect of Water-Soluble POSS on the Swelling Behavior of Hybrid PDMAEMA Nanocomposite Hydrogels

The nanosized water-soluble Oa-POSS particles were added into the PDMAEMA hydrogels by in situ radical polymerization. The gels still show obvious temperature and pH double responsiveness. The swelling behavior including swelling ratio and swelling/deswelling rate is determined by the content of added Oa-POSS. 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.
