I don't think P3HT blending with carbon nanoparticles is a good idea.
P3HT is sensitive to oxygen and moisture. Conductivity wouldn't last
long. Blending will be worse than carbon black itself.

I suggest you check Prof. Qibing Pei's paper  (UCLA) about applying
CNT as transparent electrodes for artificial muscle.

Good luck.
