Metal compound nanoparticles: Flame retardants for polymer composites

Abstract

Nanoparticles of metal compounds (zinc oxide, zinc borate, magnesium hydroxide, and layered double hydroxides) were shown to be effective flame retardants for polymers. Fillers can be used either in the pure form or as synergistic additives to phosphorus-containing flame retardants. The influence of the particle size on the flame-retardant properties of plasticized polyvinyl alcohol and polymethylmethacrylate was demonstrated.
