Definitions
- Organic-inorganic eight-hybrid material composition for synthesizing the organic-inorganic eight-hybrid material, and method for producing the organic-inorganic hybrid material
- the present invention relates to an organic-inorganic octydride material having a metal oxide matrix, and a coating composition used as a raw material of the organic-inorganic hybrid material.
- the present invention also relates to a method for producing the organic-inorganic hybrid material.
- organic and inorganic eight-hybrid materials have been actively developed as functional materials related to light, electrons, chemistry, living organisms, and the like.
- a sol-gel method is particularly attracting attention as a method for synthesizing an organic-inorganic hybrid material.
- the sol-gel method is a type of chemical reaction that produces a solid by a liquid-phase reaction. It prepares a state (sol) in which the colloid is sufficiently fluid and stable, and concentrates and evaporates the solvent, etc. This is a synthetic method that transforms into a solid state (gel) that has lost fluidity. Details of such a Solugel method can be obtained from many publications (for example, see Non-Patent Document 2).
- the sol-gel method originally attracted attention as a technique for producing glass, and is currently in practical use as a method for producing various coating films and bulk bodies (see Non-Patent Document 3).
- an inorganic matrix is used to prevent the organic skeleton from aggregating and causing phase separation. It must have some interaction with the organic backbone and be evenly dispersed.
- an organic-inorganic hybrid using an organosilicate is generally used.
- the organo silicate is a silicate in which an alkoxyl group is substituted with another organic group, and polydimethyl siloxane is typical.
- hydrolyzing and polycondensing such organosilicate it is possible to synthesize an organic-inorganic hybrid material in which an inorganic matrix and an organic skeleton are bonded (interacted) via a covalent bond. It does not cause such a phenomenon.
- An organic-inorganic hybrid material obtained from such an organosilicate has characteristics of an inorganic compound such as high heat resistance and characteristics of an organic compound such as flexibility.
- an organic-inorganic hybrid material having rubber-like properties and high heat resistance has been synthesized by using polydimethylsiloxane (see Non-Patent Document 4). Also, application to sliding members has been proposed (see Patent Document 2).
