空间电磁辐射，即大数据，既是机遇，也是挑战。收集和转化废弃的电磁能量进行高效回收在能源领域具有巨大的意义。为此，提出了一种利用导电聚合物修复磁性石墨烯(NF-P)的新的有效的修补工程方法，可控制地剪裁包括导电网络和弛豫基因在内的微观网络。实现了电磁特性的精确调整，电磁响应显著提高了52%。考察了材料内部的能量转换，构建了一种革命性的能量转换模式，巧妙地利用了材料内部储存的电能和转换后的热能，理论上吸收的电动能利用率可达100%。该贴片网络作为潜在单元器件的原型，其电磁能量转换提高了近10倍，有效带宽增加了13 GHz，覆盖了整个研究频段(2-18 GHz)。该研究为材料内部能量利用开辟了新的思路，为空间电磁能量的采集、转换和传输提供了一条新的有效途径。
Spatial electromagnetic (EM) radiation, big data, is both an opportunity and a challenge. Harvesting and converting waste EM energy for high-efficient recycling has a huge significance in the energy field. Herein, a new and effective patching engineering method using conductive polymers to repair magnetic graphene (NF-P) is proposed, tailoring the microstructure network controllably, including conductive network and relaxation genes. It realizes the precise tuning of EM property, and the EM response shows a significant increase of 52%. The energy transformation inside materials is surveyed, and a revolutionary mode of energy conversion is constructed, ingeniously utilizing the stored electrical energy and the converted heat energy inside the material with the theoretical utilization of absorbed EM energy up to 100%. The NF-P patching network serves as a prototype for a potential cell device with the EM energy conversion improved by approximate to 10 times and effective bandwidth increased by 13 GHz that covers the entire research frequency band (2-18 GHz). This research opens up a new idea for energy utilization inside materials, providing a novel and effective path for harvesting, converting and delivering spatial EM energy.
