P3HT-PS blend nanofiber FET based on electrospinning

We present the preparation of novel P3HT-PS blend nanofibers that can be utilized as active channel materials in the field effect transistors (FETs). P3HT-PS blend nanofibers were prepared using electrospinning process. The formation of nanofibers was observed under the limited conditions (in terms of solvent composition and P3HT concentration). Morphology and FET characteristics of P3HT-PS nanofibers were investigated under the effect of above two conditions. The mobility of nanofiber was increased upon the increase of P3HT composition (maximum hole mobility up to ~ 5.9×10^-4 cm²/Vs). We provide the possible explanation of nanofiber formation and FET performances for the given experimental conditions.
