摘要：
High-performance, reliable, and rollable ultraviolet (UV) photodetectors have attracted considerable attention for wireless sensor network technology. Despite the improved responsivity of UV photodetectors, high-performance rollable UV photodetectors have not been reported. This paper reports a rollable UV photodetector based on ZnAl-layered double hydroxide (LDH) nanosheets on a porous polyvinylidene fluoride (PVDF) membrane. Vertically aligned ZnAl-LDH nanosheets are grown on a porosity-controlled PVDF membrane. The UV photodetector exhibits an excellent photoresponse at wavelengths below 420 nm, even in curvature with a 0.6 mm radius. The rollable UV photodetector also shows reliable, responsive performance even after 5 000 rolling cycles, indicating the reasonable durability of the ZnAl-LDH nanosheet. The reliable photodetector performance is attributed to the elasticity of the PVDF and the strong interfacial adhesion force between the porous PVDF and ZnAl-LDH nanosheets.
