(a) Schematic of typical wet process for fabricating CNT-based TCFs, which includes CNT dispersion, film deposition and post treatment (surfactant removal and/or doping). Two examples for fabricating CNT-based TCFs: (b) vacuum filtration and alumina membrane transfer to make CNT films (reprinted with permission from [80] Copyright 2010 American Chemical Society); and (c) spray coating and post treatments of CNT films (reprinted with permission from [101], copyright 2010 Royal Society of Chemistry.)
