Fabrication and optical characterization of electrospun poly(3-buthylthiophene) nanofibers

Light-emitting poly(3-buthylthiophene) (P3BT) nanofibers were fabricated via an electrospinning method. Ten weight percent poly(ethylene oxide) (PEO) was included in a P3BT spinning solution to maintain the required viscosity for electrospinning. The formation of P3BT nanofibers was confirmed through high-resolution confocal photoluminescence imaging and spectroscopy and micro-Raman measurements performed on single strands of P3BT nanofibers. Our results show that P3BT nanofibers can be fabricated using the electrospinning method that can produce abundant continuous nanofibers.
