▎ 摘　　要

NOVELTY - Bifunctional solution-polymerized styrene-butadiene rubber/graphene oxide composite comprises mercapto groups and siloxane groups functional groups, the composite material is a dehydration condensation reaction product of bifunctional solution-polymerized styrene-butadiene rubber and graphene oxide through a mercapto group and carboxyl group. USE - The bifunctional solution-polymerized styrene-butadiene rubber/graphene oxide composite is used in tire, rubber tube, adhesive tape and rubber shoes. ADVANTAGE - The composite: solves problem of poor dispersion of graphene oxide in solution-polymerized styrene-butadiene rubber, and has improved mechanical strength; has graphene oxide layer provided with oxygen-containing groups, so it also has higher specific surface, good hydrophilicity and mechanical properties, and can avoid the occurrence of unnecessary side reaction, thus is good for ensuring that the carboxyl in the oxidation germanium is effectively combined with the mercapto in the polyester. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for preparing bifunctional solution-polymerized styrene-butadiene rubber/graphene oxide composite, comprising dispersing graphene oxide in first organic solvent to obtain graphene oxide suspension, dissolving bifunctional solution-polymerized styrene-butadiene rubber in second organic solvent to form rubber solution, where the first organic solvent and the second organic solvent are miscible or the same organic solvent, mixing the graphene oxide suspension with the rubber solution, then remove the first organic solvent and the second organic solvent to obtain a bifunctional solution-polymerized styrene-butadiene rubber/graphene oxide composite precursor, under the action of an initiator, the bifunctional solution-polymerized styrene-butadiene rubber/graphene oxide composite precursor undergoes a dehydration condensation reaction to obtain a bifunctional solution-polymerized styrene-butadiene rubber/graphene oxide composite material..
