Description
Summary:Two-dimensional materials have significant advantages in fabricating humidity sensors due to their high mechanical strength, weak interlayer interactions, high specific surface area surfaces, and abundant active sites, etc. In this paper, flexible humidity sensors based on rGO/MoS2 composite was prepared for humidity sensing. The dispersion of rGO/MoS2 composite was prepared by mixing and dispersing reduced graphene oxide (rGO) and molybdenum disulfide (MoS2). The conductive silver paste was printed onto a PET substrate by screen printing, and then the dispersion of rGO/MoS2 composite was drop-coated onto PET substrate to fabricate the humidity sensor. The prepared humidity sensor has the responsivity of 95% from 23%RH to 85%RH, with the response time of 11 s and recovery time of 14.4 s. This work demonstrates the potential of rGO/MoS2 composites for the application in high-performance humidity sensors.
