多年来，微波吸收材料因其可应用于隐身，通信和信息处理等多个领域而备受关注。微波吸收材料通常需要在纳米尺度官能化，以获得理想的介电和磁性能，诱发材料与入射电磁辐射的相互作用。美国密苏里大学堪萨斯城分校陈晓波教授和Michael Green对微波吸收纳米材料的近期研究进展进行了综述，题目为Recent progress of nanomaterials for microwave absorption，发表在Journal of Materiomics第5卷第4期。您可以点击文末“阅读全文”免费下载！

  作者不仅介绍了微波吸收的基本机理（例如介电损耗，磁损耗，介电/磁损耗耦合），衡量原则（例如，分析基础，绩效评估，共同互动途径：德拜弛豫，涡流损耗，自然共振，尺寸和形状因子），而且还适时地对各种纳米材料，例如碳纳米管，碳纤维，石墨烯，氧化物，硫化物，磷化物，碳化物，聚合物和金属有机骨架，提高微波吸收性能（例如吸收带宽，反射损耗值，吸收峰位置）的研究进展进行了综述。

    采用改变纳米材料的种类，晶体结构，颗粒尺寸和掺杂材料种类和尺度，以及调整复合材料组成比例等方法，可以复合强化纳米材料与入射电磁辐射波的相互作用，增加反射损耗。

   纳米材料与电磁波相互作用的本质最终通过给定的块体材料的介电常数和磁导率进行量化。介电常数/磁导率通常与化合物的化学组成和晶相有关。

  微波纳米吸收材料通常具有与千兆赫范围内电磁辐射相互作用的本质属性，其相互作用决定于纳米材料种类、合成参数，晶体结构，颗粒形状，粒径等。一些纳米材料自身具有较强的反射损耗。一些纳米材料需要通过外部干预提高吸波性能，其中包括化学干预法，比如元素掺杂；结构干预法，比如制备核壳结构或其它复杂形貌。纳米材料的尺寸和形貌不仅会改变介电和磁性能，还会在界面产生界面偶极子，其旋转可能会与入射微波能量相呼应，从而产生共振吸收。

   与微波相互作用的纳米材料主要分为碳，碳化物，氧化物，磷化物，聚合物和合金。目前正在研发这些材料组成的新的混合物、复合材料和结构，从而与入射电磁波产生新的响应。此外，正在扩展新的纳米材料系统，例如有机金属框架和氮化碳。

    许多文献中都强调反射损耗是最重要的参数，但是研究发现，最大反射损耗可能是由计算而来，而不是通过微调纳米材料参数，由材料介电常数和磁导率表示。鉴于此，应该优先考虑的不是最大化反射损耗，而是最大化有效带宽。这需要研发更多的纳米材料来证明这一结论的正确性。
