A procedure wherein biomolecules are used as both dispersant and coagulant for carbon nanotubes (CNTs) to enable wet‐spinning of fibers is developed (see figure). These fibers have good mechanical strength (tensile strengths up to 170 MPa) and the highest electrical conductivity (as high as 130 S cm –1 ) for as‐produced polymer‐containing CNT fibers hitherto reported.
