Abstract
Methods and apparatuses for forming linear nanoparticle arrays, and the nanoparticle formulations formed therewith, are described. The nanoparticle arrays may be incorporated into coating materials, and in one example may be provided at or near the surface of two-component polyurethane coatings for use in automotive refinish clear coats. Coatings incorporating such nanoparticles may be applied to a substrate under shear to cause the nanoparticles to arrange linearly.
