Aerosol of silica nanoparticles generated during the combustion of a polysiloxane nanocomposite

Abstract : This study focuses on the aerosol emitted during the combustion of a polysiloxane nanocomposite filled with nano-silica particles. This kind of nanocomposites has been extensively studied and developed by both universities and industries for many applications in various industrial areas such as electronic and electrical equipment. Since their production and their use, they are expected to end up in incineration waste plants and they could be involved during fire. Hence, these two combustion scenarios raise an issue concerning risks towards the combustion aerosol generated. Many articles have been published about the thermal degradation of polysiloxane nanocomposites but none of them relate to tests studying silica combustion aerosol. However, SiO2 nanoparticles are studied in the problematic of siloxane in biogas.1 The aim of our work is to investigate the behavior and the fate of the nanosilica from the polysiloxane nanocomposite during its combustion under two combustion scenarios.
