ABSTRACT:
The present invention provides a novel technology and a novel transparent material having high thermal stability, excellent pliability, surface smoothness, dimensional stability and gas barrier properties, for the technical fields of packaging materials, sealing materials and display materials, and the invention relates to an inorganic layered compound film having oriented inorganic layered compound particles, exhibiting high surface smoothness, high dimensional stability, high transparency, excellent pliability, excellent gas barrier properties and high heat resistance, that is obtained by dispersing an inorganic layered compound of high transparency and a small amount of water-soluble polymer of high transparency in water or a liquid having water as a main component thereof, to thereby obtain a homogenous dispersion containing no agglomerates, applying thereafter this dispersion onto a support having a flat and water-layered compound particles, and separating the liquid, as a dispersion medium, according to any of various solid-liquid separation methods, for example, centrifugation, filtration, vacuum drying, vacuum freeze drying, evaporation by heating or the like to thereby attain formation into a film shape, and optionally followed by methods such as drying/heating/cooling to thereby effect detachment from the support.
