LAMINAR DOUBLE HYDROXIDE-POLYMER COMPLEX

Japanese Patent JP2022170814

A

To provide a complex including laminar double hydroxides disposed in gaps of a polymer, without using the laminar double hydroxides as a crosslinker for the polymer.SOLUTION: A complex includes a water-absorbing polymer including gaps, and laminar double hydroxides disposed in the gaps and having anion-exchangeability. The laminar double hydroxides may be represented by the following general formula: [M2+1-xM'3+x(OH)2][An-x/n mH2O], where M is a divalent metal, M' is a trivalent metal, An- is an n-valent anion, m>0, n is a natural number, and 0
