Document Type and Number:
WIPO Patent Application WO/2022/181628
Kind Code:
A1
Abstract:
[Problem] To provide a dispersion of exfoliated particles in which a layered polysilicate compound is interlayer-exfoliated. [Solution] Provided are: a dispersion of exfoliated particles which includes at least one nitrogen-containing basic compound (A) which is a tertiary amine or a quaternary ammonium hydroxide having at least one alkyl group having 3 or 4 carbon atoms, and in which exfoliated particles (C) produced by interlayer-exfoliating a proton-type layered polysilicate compound (B) are dispersed in an aqueous solution (D) having 10 vol% to 90 vol% of an alcohol having 1 to 3 carbon atoms; and a film-forming composition , a porous body-forming composition , an LB film, a coating film, a self-supporting film, a proton conductor, an electrolyte membrane for fuel cells, and a porous body each containing exfoliated particles.
