In this study we investigated GO/TNC hybrid films and their tunability via TNC-mediated photocatalytic reduction of GO for resistive r.h. sensing. We introduced a straight-forward LbL-SC method to fabricate layered thin films on flexible and rigid substrates using GO At high baseline humidity, all films responded with an increase in conductance to increasing r.h. (GO/rGO)/TNP-based films showed superior sensing performance with short response times, low hysteresis, and high sensitivities, suitable to detect physiological changes in r.h.
