Surface functionalised silica nanoparticles will be tested as PIN FRs for transparent thermoplastics, such as PMMA poly(methyl methacrylate) and PC polycarbonate. The project aims to develop a PIN FR with safe environment and health profile, compatible with high transparency, for e.g. automotive and aerospace applications, without migration out of the plastic matrix nor discoloration nor odor. Commercially available silica particles and those produced in the laboratory using the Stöber process will be tested. These will be surface functionalised with phosphorus and/or nitrogen FRs by grafting of small PIN FR molecules or of polymer brushes.
