A pH and Electric Responsive Graphene Oxide Based Composite Hydrogel

摘要

The pH and electric responsive composite hydrogels were prepared by in situ polymerization in the presence of graphene oxide (GO).Their structure and properties were characterized by scanning electron microscopy,Raman microscopy and mechanical testing.The results indicate that the GO is evenly dispersed in the composite hydrogels and the mechanical properties of the GO based composite hydrogels are significantly improved.Most importantly,the composite hydrogels were responsive to external stimuli such as pH and electric field.
