▎ 摘　　要

Flexible and wearable electrical devices have attracted extensive research attention in recent years. In the device fabrication process, the low-cost and compatibility with industrialized mass production are of great importance. Herein, membrane-based flexible photodetectors (PDs) based on Polyvinylidene Fluoride filter membrane with the structure of Ag nanowires (NWs)/ZnO NWs/graphene were fabricated by a full-solution method. The built-in electric field due to the ZnO/graphene Schottky junction is in favor of the separation and transport of photo-generated carriers, leading to enhanced device performance. The I-light/I-dark ratio was as high as similar to 10(2), which is far superior to that of the reported ZnO-based fiber-shaped PDs. The PDs with remarkable flexibility can be easily attached to the human body and even can work steadily under serious bending conditions. Particularly, the photocurrent can keep 95% of the maximum value after the PD was bent 1000 times. In addition to the wearable applications, the membrane-based PD arrays can also be applied for imaging application.
