Fibers of pure poly(3-hexylthiophene) (P3HT) of 1 and 2mmdiameter, were produced from solid state processing at temperatures of 200, 150 and 100oC, i.e. up tomore than 100 oC below the melting point of P3HT (∼240 oC), using a small device reminiscent with the early stage polymer extrusion machines. The fibers produced by this method are continuous and mechanically robust.WAXS results showthat themacromolecular chains of P3HT are preferably oriented along the fiber axis. This study clearly shows, for the first time, that P3HT fibers can be processed without solvents well below the polymer’s melting temperature.This work was supported by FCT (Fundac¸ ˜ao para a Ciˆencia e Tecnologia) and by the EuropeanRegional Development Fund (FEDER) through the program COMPETE (project PTDC/CTMPOL/120843/2010
