Electrospinning of a conjugated polymer is not possible due to the absence of chain entanglement (it exists as a rigid rod conformation in a solution), which is a prerequisite for electrospinning. In the present study, fabrication of core-shell nanofibers has been done by co-electrospinning of two components such as poly(3-hexyl thiophene) (P3HT) (a conducting polymer) or P3HT/PCBM as the core and poly(vinyl pyrrolidone) (PVP) as the shell. The TEM observation and FTIR analysis confirmed the encapsulation of the P3HT within the PVP polymer. Continuous P3HT or P3HT/PCBM nanofibers have been obtained by subsequent washing of the shell polymer template in a post-treatment step. These nanofibers were tested for solar cloth applications. © 2010 Elsevier B.V.
