Abstract: A kind of flame-retardant textile-based triboelectric nanogenerator with flexible, flame retardant and noise reduction is proposed. The fiber strips composed of five layers of PTFE/silicone rubber layer, conductive cloth layer, PI layer, conductive cloth layer and flame-retardant fabric layer are prepared by traditional weaving process. The experimental results show that the open circuit voltage and short circuit current of the flame-retardant textile-based triboelectric nanogenerator(5 cm × 5 cm)are about 145.25 V and 3.25 μA, respectively. In the tap/release operating mode of the frequency range 0.5~3.0 Hz, the open circuit voltage is independent of the tapping frequency, whereas the short circuit current increases with the increase of loading frequency. The experimental result is consistent with the theoretical analysis. Meanwhile, the instantaneous power can achieve a peak value of 141.63 μW when the external load resistance is 130 MΩ.The flame-retardant textile-based triboelectric nanogenerator is used as decorative carpet material in intelligent fire escape and fire rescue system. The mechanical energy generated by walking or running makes the escape arrow light up, making it easier to find the shortest escape route. For people who cannot escape in time, the flame-retardant textile-based triboelectric nanogenerator can be knocked to send out a signal for help, so that firefighters can achieve accurate positioning search and rescue.
