摘要： 提出了一种具有柔性、阻燃性和降噪性的阻燃摩擦发电织物，利用传统编织工艺将包含有PTFE/硅胶层、导电布层、PI层、导电布层和阻燃布层5层结构的纤维条横竖交叉制备而成。实验结果表明，阻燃摩擦发电织物（5 cm×5 cm）的开路电压和短路电流分别为145.25 V和3.25 μA；在0.5～3 Hz击打/释放工作模式下，织物的开路电压值在加载频率范围内变化量较小；然而，短路电流值随着加载频率的增大而明显增大，该实验数据与理论分析结果相符合；该织物在外加负载为130 MΩ时，器件的瞬态功率能够达到141.63 μW。将阻燃摩擦发电织物作为装饰地毯材料应用在智能火灾逃生和消防救援系统中，产生的机械能可以使逃生箭头发光，便于寻找最短逃生路径，对于不能及时逃生的人员，可以敲击发电织物发出求援信号，使消防员实现精准定位搜救。

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.

Key words: fire escape, fire rescue, flame-retardant material, textile-based triboelectric nanogenerator
