In the 6G era, miniaturized and highly integrated wearable communications devices require electromagnetic materials with efficient thermal-management capability to mitigate interference (EMI) heat accumulation. Herein, we present a facile strategy for conducting by constructing directional thermal-conduction nanochannels within layer-by-layer EMI shielding film. This composite film consists of polyacrylonitrile/boron nitride nanosheets@polydopamine nanofibers covered an layer based on MXene sheets. Compared traditional in which dissipates randomly, one-dimensional fibrous structure can offer dissipation pathway. Under high-power microwave irradiation, it exhibits significantly lower temperatures, ensuring robust durable communication performance without overheating. The thin (0.43 mm thickness) achieves impressive specific surface efficiency 29,400 dB·cm2·g-1 at 18-24 GHz, effectiveness (SE) 88 dB its counterpart. addition, flexible maintains high SE after 10,000 bending times. Its lightweight, flexible, design makes suitable applications various environments. thermally conductive provides rapid effective signal systems, showcasing great potential thermal management next-generation technologies.
