METHOD FOR CONTROLLING THE MORPHOLOGY OF A POLYMER STRUCTURE USING ORGANIC SALTS SELECTED BY CONSIDERING THE DEGREE OF HYDROPHILIZATION OF COUNTER ANIONS OF ORGANIC SALTS

摘要

PURPOSE: A method for controlling the morphology of a polymer structure is provided to prepare a 3D porous structure as well as a granular structure and to control the morphology such as pores, patterns, and particle diameter of the structures.;CONSTITUTION: A method for controlling the morphology of a polymer structure comprises the steps of: selecting polymers and organic salts with low hydrophilization degree; dissolving the polymers and organic salts in an organic solvent; preparing a composite gel consisting of polymer-organic salt by removing the organic solvent; removing the organic salts from the composite gel; and drying the resultant. The organic salts are ionic salts consisting of cations([X]^+) and counter ions([Y]^-).;COPYRIGHT KIPO 2012
