Abstract

Advanced polymer/nanoparticle composites are currently of great interest because of their unique properties. The bulk properties of these materials are strongly influenced by the nature of the ultrafine filler particles–including their dispersion. A technique is presented for the de-agglomeration of chemically synthesized aluminum nitride nanoparticles and their uniforn dispersion in a polymer matrix. Detrailed mechanisms for the de-agglomeration are discussed as topics for future investigation.
