Abstract:Silica nanoparticles are being utilized to enhance the mechanical performance of polymeric materials used in the automotive and construction industries. However, cumulative effects of UV radiation will degrade the polymeric molecules, resulting in a potential for release of the nanoparticles into the environment. The health and environmental effects of the released nanoparticles from polymer nanocomposites are yet to be investigated. Preliminary results of the quantitative release of silica nanoparticles from polymer nanocomposites will be presented and discussed. The results of this study will assist in establishing an accurate and predictive model for the release of silica nanoparticles from UV-irradiated polymer nanocomposites.
