▎ 摘　　要

NOVELTY - Graphene based material manufacturing involves functionalizing graphene oxide via thiol-ene click chemistry and then dispersing in solvents. The graphene is reacted with thiol containing compound via thiol-ene click reaction between thiol group and double bond of aromatic rings in graphene oxide by one-step reaction to form functional graphene oxide. USE - Method for manufacturing graphene based material, preferably nitrogen-sulfur dual doped grapheme used in polymer composite, catalyst supporter, sensor, energy storage and water treatment areas (all claimed). ADVANTAGE - The method manufactures the graphene based material in a simple and cost-effective manner on industrial scale having improved electrical conductivity and high efficiency. DESCRIPTION OF DRAWING(S) - The drawing shows a schematic representation of the functional graphene preparation via thiol-ene click chemistry.
