Abstract Metal-organic-frameworks (MOF) derived carbon materials are usually utilized as microwave absorbers, however, the practical application of the powders in flexible devices is restricted. Herein, a facile strategy is developed for in-situ vertically grown of Co-MOF precursor on conductive carbon cloths, followed by the carbonization and sulphidation process. The synthesized flexible composites, in which intertwined carbon cloths act as the skeleton, hierarchical N-doped porous carbon nanoplates anchor on the substrate and CoS2 particles are encapsulated by graphitic carbon, exhibit ultrahigh microwave absorption because of the conductive network, hierarchical porous architecture, enhanced dipolar/interfacial polarization, multi-scattering and promoted impedance matching. The thickness of graphitic carbon can be tuned from 12 layers to 25 layers by adjusting the carbonization temperature and the flexible composites annealed at 700 °C outperform others in terms of microwave absorption performance. Typically, the maximum reflection loss (RL) is up to −59.6 dB at 2.8 mm and the effective bandwidth (RL

摘要 金属有机骨架（MOF）衍生的碳材料通常被用作微波吸收剂，但其在柔性器件中的实际应用受到限制。在此，开发了一种简便的策略，用于在导电碳布上原位垂直生长 Co-MOF 前驱体，然后进行碳化和硫化过程。合成的柔性复合材料，其中交织的碳布作为骨架，分层 N 掺杂的多孔碳纳米片锚定在基底上，CoS2 颗粒被石墨碳包裹，由于导电网络、分层多孔结构、增强的偶极/界面极化、多散射和促进阻抗匹配。通过调节碳化温度，石墨碳的厚度可以从 12 层调整到 25 层，并且在 700 °C 下退火的柔性复合材料在微波吸收性能方面优于其他材料。通常，最大反射损耗 (RL) 在 2.8 mm 处高达 −59.6 dB，有效带宽 (RL
