Recently,[7] a new scalable CNT film fabrication method has been developed: Surface-Engineered Tape Casting (SETC) technique. The SETC technique solves the main challenge of tape-casting which is the detachment of the dried and the typically sticky CNT film from the supporting-substrate. To achieve a perfect detached film, the supporting-substrate has to be engineered with micro-pyramid pore structure morphology. SETC produces large area films from any commercially available carbon nanotubes with tunable length, thickness, density and composition.
