摘　　要：为制备日间可自加热且防火性能优异的多功能光热阻燃织物,采用聚多巴胺修饰的芳砜纶非织造布作为亲水基材,Fe_(3)O_(4)作为光热功能材料,聚磷酸铵(APP)作为阻燃功能材料,通过浸渍将共沉淀法制备的Fe_(3)O_(4)微球借助黏性聚磷酸铵对其包裹功能涂层得到多功能阻燃光热织物。借助扫描电子显微镜、傅里叶变换红外光谱仪、时间-温度曲线以及点燃实验对光热阻燃织物的结构和性能进行表征,并观察织物在酸碱溶液放置后的形态以表征阻燃光热织物的耐用性。结果表明,光热阻燃织物在保持良好柔韧性的情况下,兼具Fe_(3)O_(4)优异的光热性能和APP的阻燃性能,在日间可升温至60℃以上,初遇火焰时难燃,12 s后离开火源织物自熄,并且在酸碱环境下仍保持良好的形态及耐用性。Objective In order to maintain human body temperature in harsh cold environments,there is a need for green and safe photothermal conversion textiles to convert renewable free solar energy into heat to obtain safe and efficient personal heating materials for human body heat management.At the same time,there is also a need for fire retardant properties in order to prevent fire emergencies during the photothermal conversion process.Therefore,it is of great practical importance to prepare photothermal flame retardant fabrics that can be used for long-term service.Method Herein,to prepare multifunctional photothermal flame retardant fabrics that can be self-heated during daytime and have excellent fire resistance,polydopamine(PDA)-assisted aramid(PSA)nonwoven fabrics were used as hydrophilic substrates,Fe_(3)O_(4) as the photothermal functional material and ammonium polyphosphate(APP)as the flame retardant functional material.The multifunctional flame retardant photothermal fabric obtained by wrapping the Fe_(3)O_(4) microspheres prepared by co-precipitation method with the help of viscous ammonium polyphosphate APP with a functional coating using simple impregnation.The structure and properties of the flame retardant photothermal fabric were characterized by means of scanning electron microscopy,Fourier transform infrared spectroscopy,time-temperature curves and ignition experiments,and the durability of the flame retardant photothermal fabric was characterized by observing the fabric morphology before and after placement in acid and alkali solutions.Results After the PDA treatment,the fabric surface became rougher,providing more active sites and allowing Fe_(3)O_(4) and APP to be fully loaded on the fabric surface.The characteristic peaks belonging to PDA are still present in addition to those of Fe_(3)O_(4),indicating that Fe_(3)O_(4) does not change the original structure of the PSA nonwoven fabric.The temperature change of PSA/PDA fabric and PSA/Fe_(3)O_(4)/APP fabric within 720 s of IR light irradiation.It can b
