PPT-Folie

• DC electrical conductivity (s(T)) has a negative temperature coefficient (like a metal) near room temperature; at low T a weak temperature dependence is observed, but the temperature coefficient is positive.

• Log-log plots of the reduced activation energy(W=dlns/dlnT) versus temperature show that the pristine PAni-pTsA is on the insulating side of the IM transition whereas PAni-PMMA blends are on the metallic side of the IM transition.
