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.
