Hierarchically porous polyimide/Ti₃C₂T_x film with stable electromagnetic interference shielding after resisting harsh conditions.

ABSTRACT: Polymer-based conductive nanocomposites are promising for electromagnetic interference (EMI) shielding to ensure stable operations of electronic devices and protect humans from electromagnetic radiation. Although MXenes have shown high EMI shielding performances, it remains a great challenge to construct highly efficient EMI shielding polymer/MXene composite films with minimal MXene content and high durability to harsh conditions. Here, hierarchically porous polyimide (PI)/Ti₃C₂T_x films with consecutively conductive pathways have been constructed via a unidirectional PI aerogel–assisted immersion and hot-pressing strategy. Contributed by special architectures and high conductivities, PI/Ti₃C₂T_x films with 2.0 v
