Abstract
A method for preparing coatings of thin films onto solid particle has been achieved by in-situ simultaneous nucleation and deposition of dissolved material out of supercritical fluid, resultant film formation on the solid particles suspended in the supercritical fluid, and subsequent thermal conditioning of the coating in the particles. The coating method involves an enclosed system that provides: 1) for suspension of the solid particles to be coated; 2) for dissolution of the coating material in the supercritical fluid solvent; 3) for temperature or pressure swing operations causing film deposition/coating of the suspended solid particles and; 4) additional chemical addition and/or thermal cycles providing for any additional reactions required (such as polymerization).
