Abstract

Here, we report the preparation of PEDOT:PSS-MoS2 nanocomposite thin films and their electrical resistance response under humidity conditions revealing their promising properties as humidity sensor materials. One of the most interesting features of our samples is the transition from positive to a negative electrical resistance response to humidity conditions with increasing MoS2 additions. Our confocal Raman imaging studies revealed that the presence of MoS2 yields a local charge rearrangement in the thiophenyl rings of PEDOT:PSS, in relation to the enhancement of the electrical resistance negative response as observed by impedance spectroscopy analysis. The enhancement on the negative response with increasing MoS2 additions could be explained through the increment of hole carriers in MoS2 nanosheets under humidity conditions, thus leading to an enhancement in the electrical transport along the PEDOT:PSS chains.
