电磁干扰（EMI）屏蔽材料因其在生活、国防等领域的广泛应用而受到越来越多的关注并成为研究热点。开发具有可调屏蔽效能（SE）的绿色EMI屏蔽材料是研究人员的崇高追求和巨大挑战。在这里，我们通过调整退火温度来限制 TiO2 在 Ti3C2TX 表面上的生长。这调节了偶极子和界面极化以及导电网络的结构，并改善了阻抗匹配。 Ti3C2TX/TiO2异质结构材料经过合理设计，在600℃退火温度下，在18GHz频率下实现了35.1dB的高效EMI SE。这项工作为未来设计高效、可控的绿色EMI屏蔽材料开辟了新途径。同时，这种异质结构材料作为民用、商业和军用航空航天应用的多功能绿色屏蔽材料具有巨大的潜力。
Electromagnetic interference (EMI) shielding materials are receiving more and more attentions and becoming hot research topic because of their wide range of applications in life, defense and other fields. The development of green EMI shielding materials with tunable shielding effectiveness (SE) is a high pursuit and a great challenge for researchers. Here, we restricted the growth of TiO2 on the Ti3C2Tx surface by adjusting the annealing temperature. This regulated the dipole and interface polarization and the construction of the conductive network, and improved the impedance matching. The Ti3C2Tx/TiO2 heterostructured material was rationally designed and achieved an efficient EMI SE of 35.1 dB at 18 GHz when the annealing temperature was 600 degrees C. This work develops new avenues for the future design of efficient, controllable green EMI shielding materials. Simultaneously, this heterostructured material has great potential as a versatile green shielding material for civil, commercial and military aerospace applications.
