Abstract

Two types of synthesized graphene oxide (GO) were electrophoresed using various reductants and temperature controls on the Au electrode of a quartz crystal microbalance (QCM) device for humidity detection. Characteristics of the synthesized GO, its surface morphology, and its functional groups were investigated by SEM images based on EDS and Fourier transform infrared spectra (FTIR). Structure and lattice were clear resolved using 80 kV field emission gun TEM (FEG-TEM) and electron diffraction (SAED), respectively. The resonant frequency and impedance were complementary utility to illustrate the sensitivity of various GO loaded QCM sensors. The kinetic parameters of the adsorption-desorption at a related humidity of 23–95% were extracted using the Langmuir isotherm model. In this experiment, the GO _TC synthesized by a strong reductant NaNO ₃ and temperature control was demonstrated to exhibit excellent humidity sensing sensitivity with a fast absorption-desorption rate, making it a potential candidate for moisture detection.
