[News Center] Carbon-based terahertz absorbers: Materials, applications, and perspectives

2026-01-05

太赫兹波在医学、通信、安全监控及快速传感成像等领域有广泛应用，但同时也带来了电磁污染问题。因此，有效屏蔽太赫兹辐射，尤其是具备显著吸收能力，是太赫兹技术发展的关键。本文综述了太赫兹吸收材料的研究进展、所用材料及其具体应用，特别关注了碳基材料作为太赫兹吸收剂的潜力，以填补吸收系数在10–100 cm⁻¹、折射率在3–5之间的空白。碳基材料因其多样的同素异形体形态而备受关注，其中sp²杂化碳的排列状态、碳含量及石墨碳域尺寸对太赫兹吸收性能有重要影响。文章详细探讨了太赫兹吸收的基本原理、常见材料（如绝缘体、半导体、金属）的吸收行为，并重点介绍了碳基聚合物复合材料、碳薄膜、碳基泡沫及聚合物衍生碳等材料的性能与应用。这些材料在太赫兹热源、衰减器、滤波器、雷达吸波材料及热探测器等领域具有广泛应用前景。尽管金属和碳基复合材料存在反射率高或环境稳定性差等局限，但通过聚合物热解获得的碳基材料展现出优异的太赫兹吸收性能，且可通过调控热解参数精确控制其传输与反射特性。未来，基于有机硅聚合物化学路径的富碳材料有望在太赫兹、微波及红外波段发挥更广泛的应用潜力。
