▎ 摘  要

NOVELTY - Electroconductive particles are obtained by coating the surface of polymer particles with graphene. The average coverage of the polymer particles with graphene is 0.4-0.9, preferably 0.6-0.85. USE - Electroconductive particles used for conductive resin (claimed). ADVANTAGE - The electroconductive particles have improved dispersibility in resin, and high affinity with resin thus providing conductive resin having improved mechanical strength. DETAILED DESCRIPTION - INDEPENDENT CLAIMS are included for the following: (1) manufacture of electroconductive particles, which involves reducing graphene oxide after coating polymer particles with graphene oxide; and (2) conductive resin, which is obtained by dispersing the particles in a resin.
