Synthesis and Characterization of Polymeric Graphene Quantum Dots Based Nanocomposites for Humidity Sensing

Figure 1

Image of a humidity sensor made from a single layer of PEDOT:PSS+GQDs+CNT composite film (a) and the schematic drawing of the device with the two planar electrodes (b). Humidity change is detected by the change in the current with a constant Dc-bias applied to the two electrodes.
