Özet:

 

Polypyrrole (PPy) was prepared by a chemical method by using  oxidizing agents ferric chloride and potassium persulphate, both as  films and pellets.  The effect of various variables-such as aging of  the films, film thickness, ratios of the reactants and type of the  sample (film or disc)-on DC conductivity were investigated.  The  results from samples prepared with ferric chloride exhibited an  increase in conductivity with increasing concentration of oxidizing  agent to a certain ratio, above which a slight decrease occurs.   Whereas in the case of using potassium persulphate as the oxidizing  agent, a decrease in conductivity occurs with increasing its  concentration.  Moreover, aging of the samples caused a loss of  conductivity.  In additional to the DC conductivity, both the growth  rate of PPy films and the yield of the powder samples were  investigated and were found to be dependent on the concentration of  the oxidants.
