CLAY MINERAL-BASED COMPOSITE MATERIAL AND METHOD FOR PRODUCING THE SAME

摘要

PROBLEM TO BE SOLVED: To provide a clay mineral-based composite material, and to provide a method for producing the composite material. SOLUTION: The clay mineral-based composite material is composed mainly of a clay mineral having anion-exchange ability between layers and is introduced, in the case where an alkali or alkaline-earth metal is combined with an organic compound having bioactive function, the organic compound between the layers on the stable or metastable state by exchanging with interlayer water between the layers. The method for producing the clay mineral-based composite material comprises introducing the organic compound between the layers of the clay mineral by removing the interlayer water by previously heat-treating the clay mineral and, before condensing between the layers of the clay mineral, immediately mixing the clay mineral with the organic compound or a solution thereof to introduce the organic compound between the layers of the clay mineral. The organic compound having bioactive functions is easily introduced between the layers within a short time to produce inorganic or organic composite materials with unnecessarily requiring complexing of interlayer anion with the organic compound.
