We investigated the performance of cotton fabrics coated with DOPO-HQ and Zr-based Metal-organic Frameworks when exposed to fire. The chemical structure of the cotton fabrics before and after the coating was characterized using FTIR spectroscopy, and the surface morphology of cotton and their combustion residues was probed via scanning electron microscopy. In our experiments, we used flammability tests and thermogravimetric methods to understand the burning behavior of the coated fibers, as well as their thermal stability. The cotton fabrics coated with DOPO-HQ and Zr MOFs exhibited shorter combustion times, had better thermal degradation properties, promoted the creation of heat-insulating layers, and exhibited improved smoke suppression behavior.
我们研究了涂覆有9,10-二氢-9-氧杂-10-磷杂菲-10-氧化物（DOPO-HQ）和锆基金属有机框架的棉织物在暴露于火时的性能。使用傅里叶变换红外光谱（FTIR）对涂覆前后棉织物的化学结构进行了表征，并通过扫描电子显微镜探测了棉织物及其燃烧残渣的表面形态。在我们的实验中，我们使用燃烧性测试和热重分析法来了解涂覆纤维的燃烧行为及其热稳定性。涂覆有DOPO-HQ和锆基金属有机框架的棉织物燃烧时间更短，具有更好的热降解性能，促进了隔热层的形成，并表现出更好的抑烟性能。
