摘　　要：为进一步提升金属-有机框架结构修饰改性制备功能化纤维/织物的实用性与高效性,根据金属-有机框架结构改性纤维/织物的合成工序及改性技术,分类了现阶段金属-有机框架改性纤维/织物的常用制备方法,详细剖析了现有制备方法存在的优势、缺陷和适用范围,并归纳了此类改性纤维/织物在催化、吸附分离、生物医用、能源存储、和传感检测等领域的应用,探讨了其作用机制与局限。此外,针对目前功能化金属-有机框架结构改性纤维/织物制备及应用领域所面临的挑战指出,此类改性纤维/织物的主要研究方向应聚焦于开发出更加经济化、绿色化、简便化的制备方法,同时结合改善局限上述功能化改性纤维/织物应用关键性问题,如耐候性和分离效率等,才能真正实现功能性金属-有机框架结构改性纤维/织物的工业化生产与规模化应用。Significance Metal-organic frameworks(MOFs)have garnered extensive attention owing to their highly structural design,large specific surface area,and abundant porosity,which are now recognized as one of the most promising nanomaterials and are favored in many fields such as catalysis,gas storage and separation,energy storage,antibacterial,sensing,drug delivery,and hydrophobicity.Fiber/fabrics modified with MOFs as a matric material can greatly extend the application of MOFs to overcome MOFs poor processability,and create MOFs fiber/fabric composite materials with predetermined functions.In order to further improve the practicability and efficiency of functionalized fiber/fabric modified with MOFs,research process in the preparation and application of these modified fiber/fabrics is reviewed.Progress The processing of traditional polymeric fiber materials is to melt-extrude polymer slices and obtain the final product through a series of post-processing processes.However,in the process of combining MOFs nanomaterials with polymer fiber substrates,problems such as nanoparticle agglomeration and embedding are often encountered,which hinters their specific functions.Therefore,various new preparation processes have been developed in recent years to ensure that MOFs are uniformly dispersed on the fiber surface.Based on the synthesis process of fiber/fabric modified with MOFs,these methods can be classified into two categories,i.e.,the prefabrication method and in-situ method.The prefabrication method combines the pre-synthesized fiber/fabric with MOFs by blending or post-finishing,while the in-situ method introduces additional nucleation active sites on the surface of inert fiber/fabric and allow MOFs structures to grow on the fiber/fabric surface directly.The microscopic mechanisms and advantages and disadvantages of different preparation methods are analyzed.In addition,the application of new technologies such as sorption-vapor method and fiber-intercepting-particle method in the preparation of fiber/fabric modified wi
