With the growing development of the Internet of things, wearable electronic devices have been extensively applied in civilian and military fields. As an essential component of data transmission in wearable electronics, a flexible antenna is one of the key aspects of research. Conventional metal antennas suffer from a large skin depth, and cannot satisfy the requirements of wearable electronics such as light weight, flexibility, and thinness. Recently, a group of two-dimensional metallic metal carbides (named MXenes) have been explored as building blocks for high-performance flexible antennas with excellent flexibility and superior mechanical strength. The appearance of hydrophilic functional groups at the surface of a MXene allows simple, scalable, and environmentally friendly manufacturing of MXene-based antennas. In this minireview, some pioneering works of MXene-based flexible radio frequency components are summarized, and the existing bottlenecks and the future trends of this promising field are discussed.
随着物联网的不断发展，可穿戴电子设备已在民用和军事领域得到广泛应用。作为可穿戴电子产品中数据传输的重要组成部分，柔性天线是研究的关键方面之一。传统金属天线趋肤深度大，无法满足可穿戴电子产品对重量轻、柔韧性好和轻薄的要求。最近，一类二维金属碳化物（称为MXenes）已被探索用作高性能柔性天线的构建材料，具有出色的柔韧性和卓越的机械强度。MXene表面亲水性官能团的出现使得基于MXene的天线能够进行简单、可扩展且环保的制造。在这篇综述中，总结了一些基于MXene的柔性射频组件的开创性工作，并讨论了这一有前景领域的现有瓶颈和未来趋势。
