There is considerable interest in the use of nanofibers and nanoparticles in electronic devices. These materials have potential application in sensors, actuators, and memory, to name just a few.i,ii the size of the materials used may improve sensitivity because of their high specific surface areas. The nanoparticles may also have properties that are inherently different from their bulk counterparts. The use of synthetic polymers may result in considerable mass savings over conventional metal-based systems. It is clear that these systems have many potential advantages, however, there is still a great deal to be learned about how to make and characterize them. In our laboratories, we have recently shown that it is possible to make a variety of nanostructures based on polyaniline and polypyrrole with a variety of different techniques. In the present report, we review some of our work with a focus on nanofibers, one-pot synthesis of metal nanoparticle nanocomposites, and the patterning of conductive nanofibers. We believe that these systems will be useful in novel or significantly improved devices.
