Document Type and Number:
WIPO Patent Application WO/2017/221990
Kind Code:
A1
Abstract:
Provided are: a functional layer including a layered double hydroxide (LDH), said functional layer exhibiting not only excellent ion conductivity, but also excellent alkali resistance; and a composite material provided with said functional layer. The functional layer includes a LDH, and has hydroxide ion conductivity. When the LDH is immersed in a 5 mol/L aqueous potassium hydroxide solution including zinc oxide at a concentration of 0.4 mol/L, for three weeks at 70˚C, no changes occur in the surface microstructure and the crystal structure.
