SYNTHESIS AND PROPERTIES OF INORGANIC-ORGANIC COMPLEXES - INTERCALATION COMPOUNDS OF CLAY MINERALS AND TRIMETHYLSILYL DERIVATIVES OF ORTHOSILICATE.

Two methods for preparing novel inorganic-organic complex materials were investigated; the intercalation of organic molecules into the interlamellar space of clay mineral (montmorillonite), and direct organic derivatization of orthosilicate (olivine). Some Ca-montmorillonite amino acid complex films were prepared and their volume resistivities were measured by means of a high resistance meter. The volume resistivities of these films increased with the increase in the amont of amino acid added. The volume resistivity of every heat-treated complex film was greater than that of its original complex film because of the dehydration of the adsorbed water which was thought to be the charge carrier. In the case of aminocaproic acid-montmorillonite complex, polymerization of aminocaproic acid in the interlayer space as well as the dehydration of adsorbed water by heat treatment were effective for an improvement of the insulation of montmorillonite films.
