Abstract

<abstract abstract-type="graphical" xml:lang="en" id="adma201500914-abs-0001"> <title> <x xml:space="preserve">Abstract</x> </title> <p> <bold>Increase in conductivity and mechanical properties</bold> 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. <graphic position="anchor" mimetype="image" xlink:href="ark:/27927/pgjqk1ck3d" orientation="portrait" xlink:type="simple" xmlns:xlink="http://www.w3.org/1999/xlink" /></p> </abstract>
