Conducting polymers are now widely used as electrode materials. But major problem of these electrodes are their poor electrical conductivity. It is reported composite of these materials with nanofillers improve their conductivity. So, the effect of nanofillers like graphite powder and carbon black on their electrical properties will be interesting. This chapter will highlight application potential of these composite electrodes with examples. An attempt has been made to explain how these nanofillers improve electrical conductivity.
