Abstract Zr-based metal-organic frameworks (MOFs) UIO-66-NH2 was modified with methacrylate anhydride, and then the modified MOFs were deposited onto polypropylene (PP) nonwoven fabric while real-time curing assisted by UV irradiation to prepare composite of MOFS/nonwoven fabric (PSP). The changes of crystal form and morphology of UIO-66-NH2 before and after modification were analyzed, and the binding fastness of MOFs (UIO-66-NH2-MET) to PP nonwovens was examined, and the effect of adsorption conditions on the adsorption properties of PSP composite was investigated. The results show that UIO-66-NH2-MET could be prepared through modifying the UIO-66-NH2 structure with methacrylate anhydride group. After modification, the crystal structure of MOFs remained unchanged and the original frame structure was retained. UIO-66-NH2-MET has good fastness on PP nonwovens. No mass loss occurred after repeated washing, and the PSP composite retained good adsorption effect. The optimum conditions for PSP composites to adsorb methylene blue (MB) are as follows: The initial concentration of the dye was 50 mg/L, the adsorption time was 300 min, and the pH value was 9.
