Composite structure consisting of metallic nanoparticles coated with an organic polymer; process for the production thereof

摘要

There are disclosed a metal-organic polymer composite structure, particularly a porous metal-organic polymer composite structure, for use as functional materials such as catalysts, and a method for producing the structure. The composite structure is composed of a microphase-separated structure from a block copolymer in which a metalphilic polymer chain and a metalphobic polymer chain are bonded together at each end, and ultrafine metal particles are contained in the metalphilic polymer phase of the microphase-separated structure. Preferred polymers are a poly (2-vinylpyridine) homopolymer and a block copolymer of poly (2-vinylpyridine) and polyisoprene. <IMAGE>
