Abstract
Thin films of well‐stacked two‐dimensional MXene flakes have been used in various applications, especially in sensors and microscale energy storage devices, such as micro‐supercapacitors. Miniaturization and integration of devices, as well as maximization of device performance require nanoscale patterning of MXene, beyond what can be achieved using inkjet or screen printing. However, nanoscale patterning technology for MXene is yet to be developed. In the present work, a simple fabrication method is demonstrated for manufacturing Ti3C2Tx MXene films with vertically aligned nanopatterns via soft lithography. This process involves polydimethylsiloxane (PDMS) stamping with line‐patterned PDMS molds. The feature size of the vertical line patterning of MXene is controlled with the nanometers accuracy by swelling of the PDMS mold by toluene, which also guides vertical alignment of MXene flakes. As a result, vertically aligned MXene nanopatterns are fabricated with a width of ridges less than 200 nm and 2‐µm regular spacing between the ridges. The oleylamine‐functionalized MXene flakes are also developed for better dispersion in toluene, providing a general protocol to fabricate MXene dispersions in nonpolar solvents.
A simple and comprehensive method for fabricating nanopatterns with vertical alignment of Ti3C2Tx MXene flakes is demonstrated. The feature size of the vertical patterning is controlled with the nanometers accuracy by swelling of the polydimethylsiloxane mold by toluene. The oleylamine‐functionalized MXene is developed for better dispersion in toluene, providing a general protocol to fabricate MXene dispersions in nonpolar solvents.
