Is there any polymer that is intrinsically conducting?  All the "conducting polymers" that I am aware of are doped semiconducting polymers, so that there is a continuum of electrical conductivity depending on the doping level for a given type of semiconducting polymer.  In that sense, it doesn't seem possible to categorize along a certain conductivity value, unlike with metal elements vs. semiconductor elements.

I agree, it has sense for polymer composites.

i do agree

Dear  all;

to understand this you should focus on the band gap. Each polymer has its own specifications and methods of preparation to be pure conducting or semiconducting. Regards

Thanks to all
