柔性碳化钛(Ti3C2)天线为物联网(IoT)应用的普及提供了信息通信渗透方面的突破。由于介质基板和无添加剂的Ti3C2油墨的共形集成有限，目前的配置仅限于多层复杂设计。在这里，我们报道了结合界面改性和先进的挤压印刷技术的柔性超宽带Ti3C2单极子天线。聚多巴胺作为分子胶纳米粘结剂，使Ti3C2薄膜与商业电路板紧密结合，具有较高的空间均匀性和机械柔韧性。弯曲天线恢复到平坦状态后，可以很好地保持Ti3C2天线的带宽和中心频率，在低频段增益差在±0.2dBI内波动，克服了传统的非弹性铜天线。实现了弯曲状态下流畅稳定的实时无线传输演示实例。在快速发展的物联网应用中，设计超薄而灵活的天线对于高效的无线数据通信和传输具有重要意义。报道了一种采用界面改性和先进挤压印刷技术相结合的柔性超宽带Ti3C2单极子天线。
Flexible titanium carbide (Ti3C2) antenna offers a breakthrough in the penetration of information communications for the spread of Internet of Things (IoT) applications. Current configurations are constrained to multi-layer complicated designs due to the limited conformal integration of the dielectric substrate and additive-free Ti3C2 inks. Here, we report the flexible ultrawideband Ti3C2 monopole antenna by combining strategies of interfacial modification and advanced extrusion printing technology. The polydopamine, as molecular glue nano-binder, contributes the tight adhesion interactions between Ti3C2 film and commercial circuit boards for high spatial uniformity and mechanical flexibility. The bandwidth and center frequency of Ti3C2 antenna can be well maintained and the gain differences fluctuate within ±0.2 dBi at the low frequency range after the bent antenna returns to the flat state, which conquers the traditional inelastic Cu antenna. It also achieves the demo instance for the fluent and stable real-time wireless transmission in bending states. Designing ultrathin and flexible antenna is of great interest for efficient wireless data communication and transmission at fast-growing IoT applications. The authors report a flexible ultrawideband Ti3C2 monopole antenna by combining strategies of interfacial modification and advanced extrusion printing technology.
