DECOMPOSITION METHOD OF AGGREGATION STRUCTURE, AND MANUFACTURING METHOD OF PRIMARY PARTICLES OR/AND FINE AGGREGATES CONSTITUTED OF PRIMARY PARTICLES INCLUDING THE DECOMPOSITION METHOD AS PROCESS

摘要

PROBLEM TO BE SOLVED: To provide a method for uniformly dispersing by decomposing an aggregation structure that is an aggregate of primary particles of nano order or micron order into primary particles or fine aggregates without destroying the primary particles.;SOLUTION: A decomposition method of aggregate structures is a method for suppressing destruction of primary particles, and decomposing aggregate structures by coagulating a dope containing aggregation structures formed by aggregating primary particles using a freezing liquid, in which the dope contains a polymer, a solvent that dissolves the polymer, and aggregation structures formed by agglomerating the primary particles, the coagulation liquid contains a solvent that is a poor solvent of the polymer, and in the coagulation process for mixing the dope and the coagulation liquid, the aggregate structures are decomposed.;SELECTED DRAWING: Figure 2;COPYRIGHT: (C)2017,JPO&INPIT
