Wet spinning of fibers from a solution of polyaniline doped with 2‐acrylamido‐2‐methyl‐1‐propanesulfonic acid (AMPSA) is reported. The fibers spun into selected coagulation solvents are inherently electrically conductive and can be cold drawn to extensions of >500%with a concomitant rise in electrical conductivity of ∼1500%. The fibers appear to be void free and, when drawn, the strain‐hardened fibers show final breaking strains of the order of 50 MPa. These fibers are stable in air and could be produced cheaply on an industrial scale.
