We report for the first time the use of a microfluidic supercritical antisolvent process (mu SAS) to synthesize semiconducting polymer nanoparticles (NPs) of poly(3-hexylthiophene) (P3HT). Solvent-free P3HT NPs with average diameters as small as 36 +/- 8 nmare obtained. They are continuously spray-coated on substrates to fabricate OFET devices, demonstrating hole mobility through the nanoparticle film equivalent to that of conventional spin-coated P3HT.
