sulfonated graphene (SG) as fillers mixed and coprecipitated with natural latex

the natural rubber (NR) composites filled with SG were prepared using traditional rubber manufacture. The structure and morphology of SG were tested. The mechanical property

abrasion resistance

gas resistance

and thermal property of vulcanized rubber were investigated. The results showed that there were abundance activity functional groups in the surfaces and less slice layer structure of sulfonated graphene. The mechanical and wear resistance properties of composite were improved

but the permeability and heat conductivity were fell. When the graphene addition amount was 2. 0% (wt)

the tensile strength of the composite was the largest

27. 06MPa; wear volume was 0. 08cm
