A method for decomposing an aggregated structure, and a method for producing a primary particle and / or a fine aggregate composed of the primary particle, which includes the method as a step

摘要

PROBLEM TO BE SOLVED: To provide a method for decomposing an aggregated structure, capable of decomposing an aggregated structure obtained by aggregating nano or micron order primary particles and the like into the primary particles or fine aggregates without destroying the primary particles to uniformly disperse them.SOLUTION: The method for decomposing an aggregated structure comprises shrinking gel formed from an aggregated structure containing dope containing an aggregated structure obtained by aggregating primary particles and a gelling agent. The gelling agent, a polymer, a solvent for dissolving the polymer and the aggregated structure obtained by aggregating primary particles are included in the aggregated structure containing dope.SELECTED DRAWING: Figure 16
