The present study investigated whether the doping of CNTs with nitrogen or boron can significantly influence the TE properties of their PP composites. Doping CNTs with p-type boron led to higher positive Seebeck coefficients, whereas the introduction of n-type nitrogen containing CNTs led to PP composites with negative Seebeck coefficients.
