(57) Abstract: A method for producing composite particles by a simple production process without using an organic solvent harmful to the human body or removing the organic solvent by heat treatment or the like, and the method. Providing the composite particles obtained by the method. SOLUTION: In the presence of supercritical carbon dioxide or liquefied carbon dioxide, fine particles are contacted with a fluorine-based polymer compound and / or a silicone-based polymer compound, and then the obtained mixture is expanded under reduced pressure. A method for producing composite particles of a fluoropolymer compound and / or a silicone polymer compound, and composite particles obtained by the production method. |
