摘　　要：Currently,there is an imperative demand for developing a novel flexible heater with high adhesion,breathability,and extreme condition resistance,such as ultra-high temperatures and even fire.Herein,a high-adhesion,flame-retardancy,and anti-bacteria copper nanoparticles networks/nylon 6 woven fabric(CNNs/NWF)wearable heater with a“sandwich-like”structure has been designed and fabricated based on phatic acid/aminopropyltriethoxysilane(PA/APTES)hybrid coating.On the one hand,the CNNs/NWF wearable heater exhibited superb electrothermal behavior working at a peak temperature of 208.8℃powered with 2.0 V,better than that of wearable heaters in the recently reported literature.On the other hand,the vertical burning test showed that the heater possesses splendid flame retardancy.Furthermore,the PA/APTES coating could deposit a nanoscale porous protective film on the surface of CNNs/NWF,which imparts the heater with relatively excellent oxidation resistance and breathability.In addition,the antibacterial efficiency against Escherichia coli(E.coli)and Staphylococcus aureus(S.aureus)still reached100%after 50 times of standard washing and being electrified at 2.0 V for 5 min,keeping humans away from the threat of bacterial infections.We think that the heater in this research could be extended to wearable heating devices.
