<jats:p> As an important kind of material with porous structure, metal-organic frameworks (MOFs) have been applied extensively in many fields due to their some outstanding properties. Herein, we proposed a facile approach for preparing bimetallic MOF (Ce/Fe-NH<jats:sub>2</jats:sub>-UiO-66) with excellent ultraviolet (UV)-blocking properties. Based on the as-obtained particles, flexible MOF/polyvinyl chloride (PVC) composite films were readily fabricated. According to the characterizations, these as-prepared composite films exhibited splendid performance on UV-blocking, the rhodamine B (Rh B) solution showed a much slower degradation rate under the radiation of UV light with the protection of MOF/PVC composite films, which demonstrated the distinguished UV-blocking ability of these as-prepared MOF particles, but the PVC thermal degradation is not fully developed, the UV shielding and thermal stabiliztion mechanism for PVC was discussed. Therefore, It is expected that this approach is prospective for the large-scale preparation of MOF materials with excellent UV-blocking performance. </jats:p>
