ABSTRACT
Here, we report the controllable fabrication of transparent conductive films (TCFs) for
moisture-sensing applications based on heating-rate-triggered, 3-dimensional porous conducting
networks of single-walled carbon nanotube (SWCNT)/poly(3,4-ethylenedioxythiophene)-
polystyrene sulfonate (PEDOT:PSS). How baking conditions influence the self-assembled
microstructure of the TCFs is discussed. The sensor presents high-performance properties,
including a reasonable sheet resistance (2.1 kohm/sq), a high visible-range transmittance (> 69
%, PET = 90 %), and good stability when subjected to cyclic loading (> 1000 cycles, better than
indium tin oxide film) during processing. Moreover, the benefits of these kinds of TCFs were
verified through a fully transparent, highly sensitive, rapid response, noncontact moisturesensing
device (5×5 sensing pixels).
