Interestingly, within the polytetrafluoroethylene (PTFE)-carbon nanotube (CNT)-Fe<sub>3</sub>O<sub>4</sub> layer (FCFe), CNT nanofibers interweave with PTFE fibers to form a stable "silk-like" structure that effectively captures Fe<sub>3</sub>O<sub>4</sub> particles. By incorporating a highly conductive MXene layer, the FCFe/MXene (FCFe/M) membrane exhibits excellent electrical/thermal conductivity, mechanical properties, and flame retardancy.
