Conducting Polymer Metal Nanocomposites In the past years polymers were known so for as a class of heat sensitive, flexible, electrically insulting amorphous materials. But new dimensions to present era is given by the discovery of π-conjugated conducting polymers commonly such as Polyacetylene (PA). Nowadays various conducting polymers such as Polyaniline (PANI), Polypyrrole (PPy), Polyindole, Polythiophenes etc.(See Conductive polymer) are most studied and various methods are reported such as hard template methods, soft template methods are used for the synthesis of various nanostructures. The basic conduction mechanism in conducting polymers is due to Polarons, Bipolarons and solitons. Conducting polymers are used in various applications such as Chemical sensors and Biosensors, Transistors and Switches, Data Storage devices, Photovoltaic cells, Actuators etc. But the conducting polymers metal nanocomposites open the new window for much efficient applications than their bulk counterparts. Nowadays various methods such as one pot synthesis, insitu synthesis, sonochemical synthesis  etc. were used and different type of nanostructures such as nanofibers, 1D nanocomposites  and they are used in polential applications such as sensoric, electrochromic devices etc.
