Nanocomposites of carboxyl functionalized conducting polymer, poly(anthranilic acid) (PANA), with inorganic Na+ montmorillonite (MMT) clay are formed using in-situ polymerization and solution mixing techniques and used for the first time for fabrication of sandwich type devices with configuration metal Al/PANA–clay nanocomposite/indium tin oxide coated glass (ITO). The current–voltage ($I$–$V$) characteristics and diode performance parameters are compared and contrasted for the materials obtained by different synthesis routes and polymers synthesized for different polymerization time. $I$–$V$ characteristics of these devices show a rectifying contact with Al metal, however, with significant variation in performance parameters like barrier height, ideality factor and reverse saturation current. The capacitance–voltage ($C$–$V$) characteristics of the Schottky diodes are used for extracting the built-in potential and doping concentration. The novel nanocomposite material is also characterized for their surface morphology, structural and electrical properties.
