Which is the metal nanoparticle doped, and whether the conductivity was measured by pelleting the sample or for the film..?

Which metal nano particles have been introduced by you in conducting polymer matrix? Are these simply mixing of metal nanoparticles with conducting polymer matrix or you are designing composites with conducting polymer doped with specific dopants. Generally nano[particles can be incorporated in CP matrix during polymerization stage by emulsion polymerzation or metal nanoparticles are used as a doping matrix like gold nano particles. So in what context you have used metal nanoparticles is not clear and so please go through the conducting polymers literature sincerely and you will understand the behaviour. 

simply i have mixed

any such links do u have? @ Ahmed Elabd
