Abstract
Intelligent hydrogels is as drug carrier, and it has a good application prospect. There are some changes factors in the human environment, such as temperature, pH. Therefore, the temperature sensitive hydrogels and pH sensitive hydrogels can release system for drugs in the body. So the paper detailed descripts a novel MWCNTs good dispersion of PMAA/MWCNTs nanohybrid hydrogels. The introduction of MWCNTs significantly increased the hydrogel pH response and mechanical strength, and depends on the MWCNTs component ratio, particle size and concentration of cross-linking agent. The study found, swelling rate of hybrid hydrogels was faster than the pure PMAA hydrogel, and the swelling behavior were explained. The compression stress-strain experiments should be found, MWCNTs load transfer plays an important role in improving the mechanical properties of the hybrid hydrogels network compression.
