▎ 摘　　要

NOVELTY - Composition comprises 0.05-5 %mass graphene and/or its derivatives and 80-95 %mass resin. USE - Composition e.g. powder used for surface coating of metal (all claimed) in the form of cylinder and plate. Uses include but are not limited to paints, varnishes, lacquers and enamels. ADVANTAGE - The composition reduces cost, and improves mechanical properties, thermal stability, bactericidal action and electrical properties of the coating. DETAILED DESCRIPTION - INDEPENDENT CLAIMS are included for the following: manufacture of the composition, which involves (i) homogenizing a mixture containing 0.05% to 5% by mass of graphene and/or its derivatives, such as nanoplatelets and 80-95 %mass resin, (ii) extruding the mixture, (iii) milling the mixture, and (iv) sieving the mixture; and urface coating process, which involves applying a composition to a surface.
