Ultrasonic-Assisted Diels-Alder Reaction Exfoliation of Graphite into Graphene with High Resveratrol Adsorption Capacity.

ABSTRACT: Scalable preparation of graphene with high adsorption capacity is an important prerequisite for fully realizing its commercial application. Herein, we propose an environmentally friendly route for exfoliation of graphene, which is established based on the Diels-Alder reaction. In our route, N-(4-hydroxyl phenyl) maleimide enters between the flakes as an intercalating agent and participates in the Diels-Alder reaction as a dienophile to increase the interlayer spacing of graphite. Then, graphite is exfoliated into graphene with the aid of ultrasound. The exfoliated product is hydroxyl phenyl functionalized graphene with a thickness of 0.5-1.5 nm and an average lateral size of about 500-800 nm. The exfoliation process does not involve any acid or catalyst and would be a safe and environmenta
