▎ 摘 要
Graphene oxide (GO) possesses some unique properties, which allow its technological applications in many fields (energy storage, microelectronic devices, and chemical sensors). It can also be used as a sensitive layer in the development of the chemical acoustoelectronic sensors. We characterized the produced GO films by measuring their structural properties, permittivity, and longitudinal/shear elastic moduli. For the first time, we determined the longitudinal and shear elastic moduli of a GO film under study to be 12.3 +/- 0.1MPa and 3.0 +/- 0.1MPa, respectively. The density of the GO film is equal to approximate to 850kgm(-3). The permittivity of the GO film was found to be 21 for a frequency f=20Hz. The obtained results may be used in further application of GO films in acoustoelectronic sensor devices.
