In this work, using the advantages of Fe and Co nitrates acting as nucleation sites, we polymerized acrylamide (AAm) complexes using frontal polymerization to obtain FeCo alloy/N-doped carbon composites by converting its original precursor. The results of PAAm coating were found to be extremely useful in suppressing the collapse of the FeCo microstructure during pyrolysis, resulting in a unique hierarchical FeCo@C−N core-shell nanoparticle architecture encapsulated in PAAm-derived carbon nanocages. The thermal, mechanical and magnetic properties of the resulting FeCo/C−N filling polyethylene system have been investigated and presented.

FeCo@N 掺杂纳米颗粒封装在聚丙烯酰胺衍生的碳纳米笼中作为聚乙烯系统的功能填料

在这项工作中，利用 Fe 和 Co 硝酸盐作为成核位点的优势，我们使用正面聚合法聚合丙烯酰胺 (AAm) 配合物，通过转化其原始前驱体来获得 FeCo 合金/N 掺杂的碳复合材料。发现 PAAm 涂层的结果在抑制热解过程中 FeCo 微观结构的坍塌方面非常有用，从而产生了封装在 PAAm 衍生的碳纳米笼中的独特分层 FeCo@CN 核壳纳米颗粒结构。研究并展示了所得 FeCo/CN 填充聚乙烯系统的热、机械和磁性能。
