METHOD FOR PRODUCTION OF ORGANIC-INORGANIC COMPLEX, ORGANIC-INORGANIC COMPLEX, AND POLYMERIC COMPOSITE MATERIAL

摘要

Disclosed are: a method for production of an organic-inorganic complex by intercalation of a positively charged organic compound between layers of a non-swellable layered silicate which is believed to be difficult to achieve under convenient conditions; the organic-inorganic complex; and a layered silicate/polymer nanocomposit using the organic-inorganic complex. The method comprises: step (I) wherein a hydrous layered silicate having a hydroxyl group in its crystalline structure is heat-treated at a temperature not higher than 1200°C and lower than the phase transition temperature of the silicate to dehydrate the silicate; and step (II) wherein the dehydrated layered silicate is contacted with an aqueous solution of a positively charged organic compound.
