Abstract

<abstract abstract-type="main"> <title>ABSTRACT</title> <p>Two types of nanoparticles TiO₂ and SiO₂ treated with silane coupling agents were incorporated into phenyl silicone rubber at a low concentration (≤1.0%) and cured by the room temperature vulcanized method. The results showed that treated TiO₂ or SiO₂ nanoparticles improved the ultraviolet (UV)‐shielding ability and enhanced the visible transmittance of the phenyl silicone rubber, compared with their respective untreated particles. Moreover, when comparing treated nanoparticles, TiO₂ was more responsible for augmenting the UV‐shielding ability of the phenyl silicone rubber, while SiO₂ played a more important role in increasing the transmittance of visible light. Low levels of nanoparticles reduced the dielectric constant of the nanocomposite; however, on reaching a critical concentration, increasing the nanoparticle content had the opposite effect. The thermal conductivity of nanocomposites increased linearly with the amount of treated nanoparticles, while SiO₂ nanocomposites exhibited better thermal conductivity than those of TiO₂. © 2015 Wiley Periodicals, Inc.
