摘要：

The polypyrrole (PPy)/ash (paddy husk) nano-composites were synthesized in the presence of ammonium persulphate (oxidizing agent) with various compositions 15, 30, 45 and 60 weight percents of ash in pyrrole by chemical oxidation method. The PPy/ash (45 weight percent) nano-composite has the highest a. c. conductivity. It is clearly indicates that, the ash concentration has influenced on the pure polypyrrole as well as shown the interaction between the ash particles and PPy. So, the nano-composites can be used as semicounductor and also, may find applications in micro power generator & thermo cooling as well as sensor such as humidity-/gas-sensor.
