METAL/ORGANIC POLYMER COMPOSITE STRUCTURE CONTAINING ULTRAFINE METAL PARTICLES ARRANGED IN ROW AND PROCESS FOR PRODUCING THE SAME

摘要

A metal/organic polymer composite structure comprising a micro-domain structure which comprises a block copolymer made up of two or more incompatible polymer chains bonded in an end-to-end manner and in which one of the polymer phases selectively contains ultrafine metal particles arranged in rows; and a process for producing the composite structure which comprises (i) the step of dissolving metal ions and a block copolymer comprising one or more polymer chains having an affinity for the metal and, bonded thereto in an endto-end manner, one or more polymer chains having no or little affinity for the metal in a mixed solvent in which the polymer and the metal ions are soluble and which comprises a solvent having the ability to reduce the metal ions and having a boiling point of 80 to 200 ~C and a solvent having a boiling point of 10 to 80 ~C; (ii) the step of removing the low-boiling solvent at the boiling point thereof to cause the block copolymer to form a micro-domain structure; and (iii) the step of reducing the metal ions thereafter while removing the high-boiling solvent at the boiling point thereof.
