Flexible PVDF/nylon-11 electrospun fibrous membranes with aligned ZnO nanowires as potential triboelectric nanogenerators

•A new TENGs based on PVDF-ZnO NWs/nylon-ZnO NWs was constructed with highly polar crystalline β-phase by electrospinning.•The maximum power density of ZnO NWs incorporated PVDF/nylon 11 triboelectric nanogenerator reached as high as 3.0 W/m2.•A potent and sustainable power source for portable electronic devices was demonstrated.
