Recyclable graphene oxide grafted with poly(N-isopropylacrylamide) and its enhanced selective adsorption for phenols

The hybrid self-flocculated graphene oxide (GO) with excellent self-flocculation performance has been synthesized. The recyclable GO has selective adsorptions with different phenol pollutants because of the differences of hydrogen bonds interaction and the molecule structure of the adsorbate. The self-flocculation and enhanced selective adsorption effect make the new GO reusable for the potential applications in environmental devices.
