A method for making a copolymer-wrapped nanotube coaxial fiber. The method includes supplying a first dope to a spinning nozzle; supplying a second dope to the spinning nozzle; spinning the first and second dopes as a coaxial fiber into a first wet bath; and placing the coaxial fiber into a second wet bath, which is different from the first bath. The coaxial fiber has a core including parts of the first dope and a sheath including parts of the second dope. Solvent molecules of the second wet bath penetrate the sheath and remove an acid from the core.
