Conducting microfibers of poly(3,4‐ethylenedioxythiophene) doped with poly(4‐styrene sulfonate), having a diameter ranging between 4.6 and 16 μm, were fabricated by a wet‐spinning technique. The as‐spun microfiber had no notable orientation of polymer chains with poor crystallinity, and electrical conductivity was in the order of 10 −1 S · cm −1 regardless of the diameter. Young's modulus, tensile strength, and elongation at break for the resulting microfiber were 1.1 ± 0.3 GPa, 17.2 ± 5.1 MPa, and 4.3 ± 2.3%, respectively.SEM image of a PEDOT/PSS microfiber reported here.
