Elastic Modulus and Thermal Conductivity of Thiolene/TiO₂ Nanocomposites.

ABSTRACT: Metal oxide based polymer nanocomposites find diverse applications as functional materials, and in particular thiol-ene/TiO₂ nanocomposites are promising candidates for dental restorative materials. The important mechanical and thermal properties of the nanocomposites, however, are still not well understood. In this study, the elastic modulus and thermal conductivity of thiol-ene/TiO₂ nanocomposite thin films with varying weight fractions of TiO₂ nanoparticles are investigated by using Brillouin light scattering spectroscopy and 3ω measurements, respectively. As the TiO₂ weight fraction increases from 0 to 90%, the effective elastic longitudinal modulus of the films increases from 6.2 to 37.5 GPa, and the effective thermal conductivity from 0.04
