Bimodal ligand engineering was applied in TiO2/silicone nanocomposites to independently control the nanoparticle dispersion and interface properties. The introduction of well-dispersed anthracene grafted TiO2 nanoparticles improved the AC breakdown strength and retarded the space charge accumulation in silicone rubber. A candidate mechanism of charge trapping and impact ionization of TiO2 and anthracene is proposed to explain the improvements.
