摘要:In this paper, the preparation and force sensitivity of ErGo-ZnO composite films were studied. In order to improve the application value of graphene composite film in optical devices, sensors, photocatalysis, etc., ZnO is added. In this experiment, the ErGo-ZnO film was successfully prepared by vacuum filtration. At the same time, by adjusting the self-assembled layer of the composite film and the concentration of graphene oxide in the self-assembly growth process, the optimal design parameters are further optimized. The experimental results show that the self-assembled 6 layers have the best performance of the graphene oxide concentration of 0.5mg/ml.The crystallinity of the 0.05wt% graphene oxide ErGo-ZnO composite film is obviously improved. The amount of phase in the film after axial stretching is greatly increased (from 20% before stretching to 92%). In addition, comprehensive characterization and experimental results show that the excellent mechanical properties and specific surface area of graphene oxide and the excellent compatibility with ErGo-ZnO materials are the key factors to improve the interface stress transfer efficiency. This makes the crystallinity and mechanical properties of the composite film greatly improved, and the piezoelectric properties are further enhanced, which greatly improves the application value of the graphene composite film in optical devices, sensors, photocatalysis and the like. © 2020 Institute of Physics Publishing.
