▎ 摘  要

NOVELTY - A block copolymer comprises substituted hydrocarbon repeating unit (I) and ethylene repeating unit (II). USE - Block copolymer is used for manufacturing graphene (claimed) for forming sheet used for electrical component and structural component. ADVANTAGE - The block copolymer provides graphene sheet with excellent exfoliation efficiency. DETAILED DESCRIPTION - A block copolymer comprises substituted hydrocarbon repeating unit of formula (I) and ethylene repeating unit of formula (II). X=bond or oxygen; R1,R2=H, 1-4C alkyl, carboxy, 6-20C aryl substituted by carboxy or sulfonic acid; n'=0-2; R3,R4=H, 6-20C aryl -COO-(6-20C aryl) or -COO-(1-4C alkylene)(6-20C aryl);and m,n=1-10000. When X is bond, R2=1-4C alkyl. An INDEPENDENT CLAIM is included for manufacture of graphene, which involves supplying a feed solution containing graphite and block copolymer into a high-pressure homogenizer including micro-channel.
