Production of Organized Clay

[0047]After dispersing 5 g of tetradecyl trimethyl ammonium bromide as the hydrophobic cationic compound in 50 g of pure water, 5 g of synthesized smectite (marketed by Kunimine Industries Co., Ltd., trade name: Smecton SA) as the heat-resistant flakes was added, and completely dispersed and swelled. After removing the liquid contained in the mixture by carrying out a solid-liquid separation using a centrifugal separator, 50 g of pure water was further added, dispersed, and the solid and liquid were separated again. After repeating the dispersion and the solid-liquid separation until foam was not formed, the moisture was thoroughly removed by a dryer. Thereby, hydrophilic exchangeable cations contained in the clay were exchanged with tetradecyl trimethyl ammonium ions. Organized clay having swelling properties to toluene, which is a non-polar solvent, was obtained.

[0048](Production of a Clay Thin Film)

[0049]The obtained organized clay was crushed. 5 g of the

[0050]A thin film of this example was prepared in a manner identical to that of Example 1 of the present invention, except that octadecyl triphenyl phosphonium bromide was used as the hydrophobic cations.

[0051]A thin film of this example was prepared in a manner identical to that of Example 1 of the present invention, except that 2 g of thermosetting epoxy resin was added at the same time as adding dimethyl silicone oil.
