Abstract
A method for forming a coated particle having a core particle that is fully coated by a dual-layer coating that includes an inner layer formed of a hydrophilic composition and an outer layer formed of a hydrophobic polymer. The core particles are added to a hydrophilic solution and mixed together. The hydrophobic polymer is then added to form a mixture. The mixture is sonicated to coat the particles and the coated particles are separated and dried to form meta-stable coated particles.
