abundant positively-charged nitrogen and oxygen surface functional groups, endowing AFR with a significantly higher positive tribo-polarity than the existing state-of-art polyamide-6 (PA6). A TENG comprising of optimized thin-layered AFR against a polytetrafluoroethylene (PTFE) film produced a peak-to-peak voltage of up to ~1,000 V, a current density of ~65 mA m-2, a transferred charge density of ~200 μC m-2 and an instantaneous power output (energy
pulse) of ~11 W m-2 (28.1 μJ cycle-1), respectively. The suitability of AFR was further supported through the scanning Kelvin probe force microscopy (SKPFM) measurements, which reveal a significantly higher surface potential value of 1.147 V for AFR as compared to 0.87 V for PA6 and a step-by-step increase of the surface potential with the increase of energy generation cycles. The work not only proposes a novel mouldable AFR synthesis process but also expands with excellent prospects, the current portfolio of tribo-positive materials for triboelectric energy harvesting applications.
