制备了四甲基铵皂石膜，并对其结构进行了表征。通过流延四甲基铵-皂石的水悬浮液，获得透明膜。该薄膜是由定向的硅酸盐颗粒与ab平面平行的基板。层间四甲基铵离子在层间空间中提供微孔，并且微孔在平行于硅酸盐片的方向上互连。该膜由于其透明性和各向异性的微孔结构而被认为是一种独特的光活性物质固定介质。
Tetramethylammonium saponite film has been prepared and its structure has been characterized. By casting the aqueous suspension of the tetramethylammonium–saponite, a transparent film was obtained. The film is composed of oriented silicate particles with ab planes parallel to the substrate. The interlayer tetramethylammonium ions provide micropores in the interlayer space and the micropores are interconnected in the direction parallel to the silicate sheet. The film is regarded as a unique immobilizing medium for photoactive species because of the transparency and the anisotropic microporous structure.
