• Increase in conductivity and mechanical properties of a carbon nanotube (CNT) fiber inspired by mussel‐adhesion chemistry is described. Infiltration of polydopamine into an as‐drawn CNT fiber followed by pyrolysis results in a direct insulation‐to‐conduction transformation of poly(dopamine) into pyrolyzed‐poly(dopamine) (py‐PDA), retaining the intrinsic adhesive function of catecholamine. The py‐PDA enhances both the electrical conductivity and the mechanical strength of the CNT fibers.
