摘要：
A layer-by-layer self-assembled zinc oxide (ZnO)/graphene oxide (GO) film device for ultrahigh humidity sensing was demonstrated in this letter. The morphological and compositional properties of as-prepared ZnO/GO hybrid were characterized by SEM and X-ray diffraction (XRD). The sensing performance of the ZnO/GO hybrid film device toward humidity was investigated, and an unprecedented response was yielded, which surpasses the existing conventional humidity devices. Moreover, this device exhibits ultrafast response and recovery speed capable of detecting human breath, acceptable repeatability, and satisfying stability. The humidity-sensing mechanism of the ZnO/GO composite device was discussed.
