LAYERED DOUBLE HYDROXIDE, LAYERED DOUBLE HYDROXIDE DENSE FILM, AND COMPOSITE MATERIAL

Document Type and Number:

WIPO Patent Application WO/2016/167030

Kind Code:

A1

Abstract:

Provided are a layered double hydroxide having improved conductivity, a layered double hydroxide, and a composite material provided therewith. This layered double hydroxide is represented by general formula (Mg2+ (1 - y)M1α+ y)1 - x(Al3+ (1 - z)M2β+ z)x(OH)2An- x/n·mH2O, where 0.1 ≤ x ≤ 0.4, 0 ≤ y ≤ 0.95, 0 ≤ z ≤ 0.95, but y and z are not simultaneously 0, α = 1 or 2, β = 2 or 3, An- is an n-valent anion (where n is an integer of 1 or higher), m ≥ 0, M1α+ is at least one substitution element cation selected from the group consisting of monovalent elements, transition metal elements, and other elements having an ionic radius greater than Mg2+, and M2β+ is at least one cation selected from the group consisting of divalent elements, transition metal elements, and other elements having an ionic radius greater than Al3+.
