Paper Abstract

Recently conjugated polymers and conjugated organic molecules have drawn a great deal of attention, since they are uniquely suited for thin film, large area, mechanically flexible devices. On the other hand, polymer/inorganic nanocomposite have also been pursued to deliver unique electronic properties in various device applications such as organic light-emitting diodes, organic thin film transistors, and solar cells. Here we demonstrate a nanocomposite based on polyaniline nanofibers decorated with gold nanoparticles and apply this composite into memory devices. The electronic property shows an electric bistable effect in a two terminal sandwiched structure. These two bistable states have different conductivities by three orders of magnitude. The mechanism is likely involving electric-field induced charge transfer between the polymer and nanoparticles. This nanocomposite material provides a unique functionality and possibility to open a new direction for future organic electronics.
