Abstract:
Nanoparticles can be incorporated into polymeric coatings to enable significant improvement in targeted properties, i.e., scratch resistance, UV resistance, conductivity, etc. Commercial processing methods have been developed to surface treat nanoparticles to render compatibility between the nanoparticle and polymer matrix to control the average particle size and particle size distribution of the dispersed nanoparticles. In addition, commercial processes to disperse the surface treated nanoparticles have been developed. These integrated technologies allow transparent coatings containing nanoparticles to be formed in a wide range of resin formulations. This paper will address the preparation and analytical characterization of nanoparticle dispersions, as well as their performance attributes.
