METHOD FOR PREPARING DIBLOCK COPOLYMER NANOPARTICLES BY USING A PRECIPITATION METHOD CAPABLE OF PRODUCING MONODISPERSE EVEN PARTICLES WITHOUT COALESCENCE

摘要

PURPOSE: A method for preparing diblock copolymer nanoparticles is provided to produce even diblock copolymer nanoparticles with a simple process and mass production.;CONSTITUTION: A method for preparing diblock copolymer nanoparticles comprises the steps of: dissolving an A-B diblock copolymer satisfying the inequality 1: ¦δA-δB¦=3 and the inequality 2: δA = 19 in a common solvent satisfying the inequality 3: δA δcommon solvent δB; and churning and dropping a non-solvent satisfying the inequality 4: δnon-solvent -δA = 3 in the A-B diblock copolymer solution. In the inequality 1, δ represents the solubility parameter (unit: MPa^0.5) of the A block and B block of the A-B diblock copolymer composed of an A block and a B block.;COPYRIGHT KIPO 2013
