微环境的小型化和对现代电子产品日益增长的需求重新激发了寻找新的候选人来满足这些需求。MXene （Mn+1XnTx）系列由于其独特的优越性能组合而被视为微电子领域的下一个主要参与者。通过简单、经济高效的处理将微电子技术整合到微图案结构中，也增加了在智能设备和微系统中使用微电子技术的可能性。这篇简短的通讯报道了碳化钛（Ti3AlC2）基MXene的纳米颗粒合成、悬浮处理和3D打印，以及其元素粉末的衍生物。更重要的是，采用原位刻蚀法制备了多层MXene (Ti3C2Tx)，显示了制备分层Ti3C2Tx纳米片的高效率。之后，水基Ti3C2Tx油墨在不同浓度（即30 mg mL - 1,50 mg mL - 1,100 mg mL - 1和200 mg mL - 1）下进行了优化的流变性研究。然后使用基于墨水书写的3D打印方法在玻璃或聚合物涂层基板上进行MXene薄层的微图图化，展示了不同应变和能量存储能力下的各向异性电性能，并显示出3D打印设备的巨大潜力。
The miniaturization of microenvironments and increasing demands on modern-day electronics have reinvigorated the search for new candidates to meet these needs. The MXene (Mn+1XnTx) family has been seen as the next major player in the field of microelectronics due to the unique combination of superior properties. Incorporating microelectronics in micropatterned structures via simple, cost-efficient processing also increases the possibilities of using them in smart devices and microsystems. This short communication reports the nanoparticle synthesis, suspension processing, and 3D printing of a titanium carbide (Ti3AlC2)-based MXene, with the derivation from its elemental powders. More importantly, the in situ etching method was employed to create a multi-layered MXene (Ti3C2Tx), showing high efficiency in generating delaminated Ti3C2Tx nanosheets. Afterward, water-based Ti3C2Tx inks were examined in varying (i.e., 30 mg mL−1, 50 mg mL−1, 100 mg mL−1, and 200 mg mL−1) concentrations for optimized rheologies. An ink-writing-based 3D printing method was then used for micropatterning MXene thin-layers on glass or polymer-coated substrates, demonstrating anisotropic electrical properties over varying strain and energy storage capabilities and showing enormous potential for 3D printable devices.
