Preparation of organic polymer/inorganic oxide conductive composites

Abstract

Preparation of conductive composites based on organic conducting polymer and inorganic oxide has been described. The composite materials thus prepared have been characterized by a wide range of experimental techniques including

elemental analysis, density measurement, UV- vis and IR spectroscopy, X-ray and sedimentometry. Even after incorporating insulating silica, the composites exhibit electrical conductivity comparable to that of the conventional semiconductors. In contrast to the bulk polymer, the composites show relatively superior environmental stability when exposed to ambient atmosphere. The composites have been further characterized for their surface area; in this connection, adsorption of methylene blue on a composite matrix has been examined.
