METAL/ORGANIC POLYMER COMPOSITE STRUCTURE CONTAINING METAL ULTRAFINE PARTICLE ARRANGED IN ROW AND PREPARATION THEREOF

摘要

PROBLEM TO BE SOLVED: To provide a technique for obtaining an easily prepared metal/organic polymer complex structure wherein metal ultrafine particles are regularly arranged in one of the polymer phases in a micro phase-separation structure, by using a micro phase-separation structure which is formed from a block copolymer. SOLUTION: A micro phase-separation structure of a block copolymer which is a lamellar structure is prepared through a process comprising 1)a step wherein a block copolymer wherein a polymer chain having an affinity for metals and a polymer chain having a low or no affinity for metals are mutually linked at their ends and a metal ion are dissolved in a mixed solvent comprising a high-boiling point solvent and a low boiling point solvent, both of which reduce metals and dissolve the above-mentioned block copolymer and the metal ion, 2) a step wherein the low-boiling point solvent is removed at a low temperature to form a micro phase-separation structure of the block copolymer and 3) a step wherein the metal ion is reduced while the high-boiling point solvent is removed at a high temperature.
