摘要

Abstract

The SiO

nanoparticles were coated on the surface of graphene oxide (GO) by sol-gel method to get the SiO

-G compound. The SiO

-G was restored and oleophylically modified to prepare hydrophobic modified SiO

-G (HM-SiO

-G) which was subsequently added to silicone rubber matrix to prepare two-component room temperature vulcanized (RTV-2) thermal conductive silicone rubber. The morphology

chemical structure and dispersity of the modified graphene were characterized with SEM

FTIR

Raman

and XPS methods. In addition

the heat-resistance behavior

mechanical properties

thermal conductivity

and electrical conductivity of the RTV-2 silicone rubber were also studied systematically. The results showed that the SiO

nanoparticles were coated on graphene oxide successfully

and HM-SiO

-G was uniformly dispersed in RTV-2 silicone rubber. The addition of HM-SiO

-G could effectively improve the thermal stability

mechanical properties and thermal conductivity of RTV-2 silicone rubber and had no great influence on the electrical insulation performance.
