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.COPYRIGHT: (C)2008,JPO&INPIT【課題】粘土鉱物系複合材料とその製造方法を提供する。【解決手段】層間に陽イオン交換能をもつ粘土鉱物を主原料として、層間にある層間水と交換して、アルカリもしくはアルカリ土類金属と生理活性機能をもつ有機化合物との組み合わせにおいて、層間に該有機化合物が安定ないし準安定な状態で導入されていることを特徴とする粘土鉱物系複合材料、及び粘土鉱物を予め熱処理することにより層間水を排除した後に、該粘土鉱物の層間が復水する前に、該粘土鉱物を有機化合物もしくはその溶液と直ちに混合することにより、該粘土鉱物の層間に有機化合物を導入することを特徴とする粘土鉱物系複合材料の製造方法。【効果】生理活性機能をもつ有機化合物を、層間陽イオンと有機化合物との錯体化を必ずしも必要とせずに、容易に短時間で層間に導入し、無機・有機複合材料を作製することができる。【選択図】図1
