Stimuli-responsive material undergoes interesting structural changes upon temperature, pH etc. Among them, temperature responsive material is convenient and less dependent on the chemical environment. Their applications have extended from drug release, smart windows, and other fields. Graphene based thermal-responsive material nanocomposite has prompted the development of thermal-responsive material because graphene has superior electrical, thermal and mechanical performance. In order to impart the stimuli-responsive ability to graphene, the common method is graphene functionalization by stimuli-responsive polymer. Non-covalent functionalization method is preferred for dispersing graphene simply. In this study, we synthesized poly((styrene)-block-(2-dimethyl(aminoethyl methacrylate (DMAEMA))) and prepared thermal responsive graphene by non-covalent functionalization. Furthermore, we tuned the low critical solution temperature using quaternization of DMAEMA moieties in block copolymer. |
