A composite material comprising a layered double hydroxide

The present invention provides a composite material comprising the layered double hydroxide, which comprises a porous base material and a functional layer, the functional layer is formed on a porous substrate and / or the porous substrate, which comprises to pass formula: M2 + 1-xM3 + x (OH) 2An-x / n · mH2O (wherein, M2 + is a bivalent cation, M3 + is a trivalent cation, An- is an n-valent anion, n is 1 or more the layered double hydroxide integer, x is from 0.1 to 0.4) represented by the interface between the functional layer and the vicinity thereof is also porous base material containing a sulfur (S). According to the present invention can provide a significantly improved conductivity of the LDH-containing functional layer is formed on a porous substrate and / or the porous substrate, a composite material containing LDH.
