Impact of vinyl concentration of a silicone rubber on the properties of the graphene oxide filled silicone rubber composites

The silicone rubber (SR)/graphene oxide (GO) composites were prepared in the present study and the properties of the composites were subsequently investigated. The effect of vinyl concentration of the silicone rubber on the mechanical properties of the prepared composites was studied specifically. It was found that the GO sheets could be uniformly dispersed within the SR matrix, increasing both the thermal and mechanical properties of the SR composites at the same time. It was also investigated that when mixing SRs with different vinyl concentrations together, the mechanical properties of the prepared rubber hybrids and their GO filled composites improved more obviously than those of the SR composites with single vinyl concentration. This study provides more application potentials for the GO in the SR industry.
