Poly(N-isopropylacrylamide) on two-dimensional graphene oxide surfaces

Poly(N-isopropylacrylamide) (PNIPAM)–graphene oxide (GO) hybrids were successfully prepared. The structural reorganization behavior of GO–PNIPAM is dependent on the water content in the GO–PNIPAM hybrids. Reversible switching of its wettability on exposure to NIR light was also demonstrated.
