Popis:	A TiO 2 /silicone rubber (SR) nanocomposite was prepared via three-roll grinding followed compressive molding technology. The TiO 2 nanoparticles were chemically modified with silane couple agent and the modification effect on the dielectric and mechanical properties of the resultant composites was investigated. The results showed that the electrical breakdown strength and ultimate tensile strength of the modified TiO 2 (m-TiO 2 )/SR nanocomposites enhanced significantly while the dielectric loss decreased relative to the naked TiO 2 (n-TiO 2 )/SR nanocomposites. These results were well correlated to the uniform dispersion state of the m-TiO 2 as well as the remarkably enhanced interfacial interaction thanks to the presence of the silane couple agent.
