Electrical properties of CNT assemblies. (a) Resistance per length changes with cross-section area of CNT bundles; (b) typical - curve of CNT films; (c) electrical conductivity variation along the length and conductivity dependence on fiber twisting (CNT fiber A, fiber B, and fiber C are spun with the same drawing speed but with different twisting speed of 250 rpm, 200 rpm, and 170 rpm, resp.).
