Method for producing inorganic-organic hybrid particle
An object of the present invention is to provide an inorganic-organic hybrid particle which has a structure where an organic material composed of two or more different components forms separate phases, wherein an inorganic material is included in the phase, and a method for producing the inorganic-organic hybrid particle. The above object is solved by an inorganic-organic hybrid particle which has a structure where an organic material composed of two or more different components forms separate phases, wherein one or more inorganic materials are included in at least one phase.
1. A method for producing an inorganic-organic hybrid particle having a particle size of 10 nm to 100 μm, which comprises: (1) to a solution containing an organic material composed of two or more different components dissolved in a good solvent, adding a poor solvent of an organic material compatible with the good solvent, evaporating the good solvent, and obtaining an organic particle which has a structure where the organic material forms separate phases; (2) mixing the organic particle with a salt of at least one inorganic material capable of coordinating to at least one organic component to obtain an inorganic-ion-organic hybrid particle; and (3) reducing the inorganic-ion-organic hybrid particle to obtain an inorganic-organic hybrid particle.
2. The production method according to claim 1 , wherein the inorganic material is microparticle having particle size of 0.5 nm to 100 nm.
3. The production method according to claim 1 , wherein the inorganic material is metal, metal compound, or alloy.
4. The production method according to claim 1 , wherein the organic material composed of two or more different components is composed of two or more different monopolymer components.
5. The production method according to claim 1 , wherein the organic material composed of two or more different components is a block copolymer composed of two or more different organic materials.
