MXene‐based films are prevalent in a variety of applications owing to their advantages such as high metallic conductivity and unique mechanical properties. However, the stability issue is the primary drawback that greatly constrains their practical applications. In this study, an MXene‐based film featuring excellent stability, high conductivity, and remarkable flexibility is designed and fabricated. It is worth noting that this film, denoted as MX‐GO(l/s), is afforded via the rational combination of mixed‐sized graphene oxide (GO) nanosheets with MXene layers. Comprehensive explorations reveal that compact and highly dense structures are formed in MX‐GO(l/s), which is ascribed to the synergistic effect of both electrostatic repulsion and intercalation. Furthermore, the exceptional stability of MX‐GO(l/s) is demonstrated by the high retention rates in conductivity under a 90‐day exposure in air and a 12‐h immersion in seawater, which are determined as 98% and 92%, respectively. The radio frequency identification (RFID) antenna based on MX‐GO(l/s) is fabricated and evaluated, showing great potential in practical applications. This study paves the way for the further development of MXene‐based films via controlled addition of the second phase, which is beneficial for their broad application prospects.

混合尺寸的氧化石墨烯诱导出具有高导电性和卓越稳定性的高致密化 MXene 基薄膜

MXene 基薄膜由于具有高金属导电性和独特的机械性能等优点，在各种应用中都很普遍。然而，稳定性问题是极大限制其实际应用的主要缺点。在这项研究中，设计和制造了一种具有优异稳定性、高导电性和卓越柔韧性的 MXene 基薄膜。值得注意的是，这种薄膜，表示为 MX-GO(l/s)，是通过混合尺寸的氧化石墨烯（GO）纳米片与 MXene 层的合理组合而获得的。综合探索表明，MX-GO(l/s)中形成了致密且高致密的结构，这归因于静电斥力和插层的协同作用。此外，在空气中暴露 90 天和在海水中浸泡 12 小时时，电导率保留率高达 98% 和 92%，证明了 MX-GO(l/s) 的卓越稳定性。分别。基于MX-GO(l/s)的射频识别(RFID)天线已被制造和评估，在实际应用中显示出巨大的潜力。这项研究为通过控制第二相的添加进一步开发MXene基薄膜铺平了道路，这有利于其广阔的应用前景。
