  Abstract

Using electrospinning, bio-based polyamide 56 (PA56) and polyamide 510 (PA510) were fabricated into nanofiber membranes for use as positive electrode materials in triboelectric nanogenerators (TENGs). The results showed that under a mass fraction of 6%, a voltage of 10 kV, a flow rate of 0.8 mL/h, and a collecting distance of 15 cm, the PA56 nanofiber membrane exhibited uniform morphology with an average fiber diameter of 326.9 ± 6.6 nm. Similarly, under the same mass fraction, voltage, and collecting distance but with a flow rate of 1.0 mL/h, the PA510 membrane also showed good morphology, with an average fiber diameter of 546.5 ± 10.5 nm. At 4 Hz, the PA56-based TENG generated a maximum open-circuit voltage of 17.1 V and a short-circuit current of 2.1 μA, while the PA510-based TENG produced 25.2 V and 2.4 μA. In wearable applications, the PA510-based TENG produced open-circuit voltages of 3.5 V, 2.1 V, 4.9 V, and 3.4 V during simulated arm swinging, elbow bending, hand clapping, and walking motions, respectively, and successfully powered patterned LED displays. After 100 mechanical cycles, the output voltage of PA56- and PA510-based TENGs decreased by 7.5% and 9.1%, respectively, due to fiber surface damage. Both TENGs maintained stable open-circuit voltages over 120 days of sealed storage at room temperature.
