Abstract：The accelerated development of electronic devices and digital technology has led to increasingly severe electromagnetic radiation interference,which not only affects the performance of electronic compo-nents but also poses risks to human physical and mental health.Polyurethane-based electromagnetic inter-ference shielding materials have garnered significant attention due to their merits,such as anticorrosion,tunable molecular structure,and stable properties.This review examines the preparation methods of poly-urethane-based electromagnetic interference shielding materials with conductive fillers,magnetic fillers,and electromagnetic hybrid fillers.The effect of microstructure and filler types on the shielding effective-ness of these materials has been discussed and the key challenges and future prospects are summarized.
