Elucidation of rGO incorporation on structural, morphological and optical properties of rGO/ZnO nanocomposites for flexible humidity sensor applications / A. Shamsul Rahimi A. Subki ... [et al.]

The effect on structural, morphological and optical characteristics towards humidity sensing capability was elucidated as humidity-sensitive sensing material that is made by composting zinc oxide nanostructured powder (ZN) nanoparticles with varying capacities of reduced graphene oxide (rGO). The ZN...
