Abstract：The fullutilization of marine uraniumresources holds significant strategic importance for sustainable nuclear energydevelopment.However，achieving eficient uranium extraction fromseawaterremains highlychallenging becauseof theultra-low uranium concentration，complex ionic environment，and microbial fouling in marine ecosystems.Todate， numerous advanced materials with exceptional extraction performance havebeendeveloped.Among these，polymer materials haveemergedasoneofthe most promisingcandidates for industrial-scale seawater uranium extraction，owing to their scalableproduction，tunablearchitecture，andsuperior bindingafnities.From thepoint of structural designand functionalization strategies，thisreview presents an overview of the latest advancements in the polymer-based uranium extraction materialsand the methodologies towards the function-oriented developmentofuraniumadsorbentswith high adsorption capacity，selectivity，and biofouling resistance，along with various emerging polymer-enabled seawater uranium extractiontechnologies.Furthermore，thecritical technicalchallngesandfutureresearchdirections inthedevelopmentof polymer-based uranium extraction materials are thoroughly elucidated.
