Abstract

Highlights

Investigation of dispersing solvents on processing Ti₃C₂T_x thin films revealed that deionized water is superior to realize tight stacking and high orientation of MXene nanosheets.
A simultaneous elevation of Seebeck coefficient and electrical conductivity of neat Ti₃C₂T_x films is achieved by increasing the centrifugal speed of MXene aqueous suspensions due to the energy filtering effect.
Further construction of Ti₃C₂T_x nanocomposites significantly strengthens Seebeck coefficient yet disrupts the stacking of MXene nanosheets.

通过精细调节纳米片的堆叠来热电调制整齐Ti3C2Tx MXenes

对制备Ti3C2Tx薄膜的分散溶剂的研究表明，去离子水更有利于实现MXene纳米片的紧密堆积和高取向。通过提高MXene水悬浮液的离心速度，由于能量过滤作用，可以同时提高整洁Ti3C2Tx膜的塞贝克系数和电导率。进一步构建Ti3C2Tx纳米复合材料显著增强了塞贝克系数，但破坏了MXene纳米片的堆积。

期刊介绍： Nano-Micro Letters is a peer-reviewed, international, interdisciplinary, and open-access journal published under the SpringerOpen brand. Nano-Micro Letters focuses on the science, experiments, engineering, technologies, and applications of nano- or microscale structures and systems in various fields such as physics, chemistry, biology, material science, and pharmacy.It also explores the expanding interfaces between these fields. Nano-Micro Letters particularly emphasizes the bottom-up approach in the length scale from nano to micro. This approach is crucial for achieving industrial applications in nanotechnology, as it involves the assembly, modification, and control of nanostructures on a microscale.
