The most promising material for uranium extraction from saltwater is generally acknowledged to be fibrous adsorbents. An irradiation-modified anti-biofouling ultra-high-molecular-weight polyethylene (UHMWPE-g-PGAO) adsorbent with a hyperbranched structure was synthesized. It exhibited adsorption capacities of 314.8 mg-U/g-Ads in aqueous solution and 4.04 simulated seawater over 28-day period. (UHMWPE) fiber functionalized by covalently linking polyethyleneimine (h-PEI) facilitate the migration uranyl ions within fibers. Additionally, amidoxime quaternary ammonium groups were immobilized on surface enhance affinity provide defense against marine organisms. This three-dimensional design h-PEI-modified UHMWPE retained more than 91.0% its maximum capacity after undergoing five adsorption-desorption cycles. UHMWPE-g-PGAO exhibits significant antibacterial activity Escherichia coli Staphylococcus aureus, achieving an inactivation efficiency 99.9%. proved innovative biofouling resistance, robustness, reusability.
