Multifunctional Janus-Structured Polytetrafluoroethylene-Carbon Nanotube-Fe₃O₄/MXene Membranes for Enhanced EMI Shielding and Thermal Management.

ABSTRACT: Herein, a novel Janus-structured multifunctional membrane with integrated electromagnetic interference (EMI) shielding and personalized thermal management is fabricated using shear-induced in situ fibrillation and vacuum-assisted filtration. Interestingly, within the polytetrafluoroethylene (PTFE)-carbon nanotube (CNT)-Fe₃O₄ layer (FCFe), CNT nanofibers interweave with PTFE fibers to form a stable "silk-like" structure that effectively captures Fe₃O₄ particles. By incorporating a highly conductive MXene layer, the FCFe/MXene (FCFe/M) membrane exhibits excellent electrical/thermal conductivity, mechanical properties, and flame retardancy. Impressively, benefiting from the rational regulation of component proportions and the design of a Janus struc
