Popis: Triboelectric nanogenerator (TENG), one of the latest and most effective technologies to harvest green energy in the industrialization and modernization era, converts mechanical energy to electricity through triboelectrification and electrostatic induction. Herein, highly porous poly(vinylidene fluoride-co-hexafluoropropylene) (PDVF-co-HFP) as a negatively charged tribomaterial was assembled with microdome-patterned chitosan as a positively charged surface to fabricate TENG and examine its mechanical and electrical properties. The results revealed that the porous PVDF-co-HFP-based TENG could generate a maximum instantaneous power of 3 mW and an open-circuit voltage of 200 V, which is 4 times higher than that made from flat PVDF-co-HFP and could light up 102 LEDs. The newly developed PVDF-co-HFP-based TENG achieves a great convergence between excellent flexibility, scalability, and superior electrical output, which has great application potential in wearable electronic devices.
