METHOD FOR PREPARING PHASE CHANGE MATERIAL NANOCAPSULE IMMOBILIZED METAL NANOPARTICLES OVERALL BY USING FUSION PROCESS OF REDUCTION OF METAL ION AND CAPSULATION

摘要

PURPOSE: A method for manufacturing nano-complex capsules, the nano-complex capsules manufactured by the same, products including the nano-capsules are provided to improve heat transferring capability and to shorten times required for manufacturing processes. CONSTITUTION: Phase transition materials, monomer, emulsion containing metal precursors and reducing agents, and chain extenders are mixed to be polymerized. The mixed ratio of the phase transition materials and the monomer is 5:1 to 1:1 based on weight ratio. The monomer is a compound containing two or more isocyanate groups. The content of the metal precursors is 0.01 to 1 parts by weight based on 100 parts by weight of the emulsion. The content of the reducing agents is 0.003 to 0.4 parts by weight based on 100 parts by weight of the emulsion. The chain extruders are compounds. Two or more amine groups are positioned at the end of the compounds. The content of the chain extruders is 1 to 10 parts by weight based on 100 parts by weight of the emulsion.
