摘要

以磺化石墨烯为填料，将其填充到天然胶乳中，混合均匀后共沉淀，采用传统橡胶加工方法制备了天然橡胶复合材料。对磺化石墨烯的结构和形貌进行了表征，测定了硫化胶的力学性能、耐磨性能、透气性能和导热性能。研究结果表明：磺化石墨烯表面含有丰富的活性官能团，为少层片状结构，硫化胶的力学性能、耐磨性得到了提高，而透气性和导热性有所下降。当石墨烯添加量为2.0%(wt)时，复合材料的拉伸强度最大为27.06MPa；磨耗体积仅为0. 08cm

；导热系数最小为0. 42W/(m•K)；透气量最低，为1. 98 × 10

Abstract

In this paper

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

; thermal conductivity is 0.42W/Mk; permeability coefficient was 1. 98 × 10
