通信和电子技术的快速发展对电磁辐射防护提出了新的迫切要求。二维过渡金属碳化物和氮化物MXene于2016年进入该领域，并迅速重塑了该领域。在此，我们就MXene系列在电磁干扰防护（包括电磁干扰（EMI）屏蔽和微波吸收）方面的最新进展和挑战进行了展望。我们研究了MXene的固有电子和介电性质，这对于电磁响应的基本理解至关重要。通过跟踪最先进的设计策略，我们探索如何优化MXene基EMI屏蔽和微波吸收材料。特别是，我们强调了电磁防护的指标和基本机制，旨在澄清常见的误解，并客观地评估报告材料的性能。最后，我们讨论了需要解决的挑战，并展望了未来的机会，在电磁辐射防护MXene的发展。
The rapid development of communication and electronic technologies has brought forward new and compelling demands for electromagnetic radiation protection. Two-dimensional transition metal carbides and nitrides known as MXenes entered the field in 2016 and have been quickly reshaping it. Here, we provide a perspective on recent progress and challenges of the MXene family for protection against electromagnetic jamming, including electromagnetic interference (EMI) shielding and microwave absorption. We examine the intrinsic electronic and dielectric properties of MXenes, which are of critical importance for fundamental understanding of electro-magnetic response. By tracing the state-of-the-art design strategies, we explore how to optimize MXene-based EMI shielding and microwave absorption materials. Particularly, we highlight the metrics and fundamental mechanisms of electromagnetic protection, aimed to clarifying common misconceptions, and objectively assess the performance of the reported materials. Finally, we discuss challenges to be addressed and give an outlook to future opportunities in the development of MXenes for electromagnetic radiation protection.
