Abstract

Aqueous-dispersed graphene/Fe3O4 hybrids are prepared using a two-step method. Functional microgels composed of the poly(N-isopropylacrylamide) (PNIPAAm) and the as-prepared graphene/Fe3O4 hybrids are synthesized in a microfluidic reactor for the first time. The microgel exhibits a good response to an external magnet and near-infrared (NIR) laser irradiation, indicating that it could be used as a light-driven and magnetic controlled switch for applications in microreactors.
