Nanofiber field-effect transistors (FETs) based on crystalline poly(3-hexylthiophene) (P3HT) and poly(stearyl acrylates) (PSA) or poly(n-lauryl acrylate) (PnLA) blends are fabricated via coaxial electrospinning (ES). The maximum FET mobility is obtained for P3HT/PSA (1:0.2) blends. The crystalline PSA promotes the larger crystallinity of P3HT in the ES nanofibers, which subsequently leads to the observation of higher mobility and improves the air stability.
