Discontinuous Dewetting, Template-Guided Self-Assembly, and Liquid Bridge-Transfer Printing of High-Resolution Single-Walled Carbon Nanotube Lines for Next-Generation Electrodes and Interconnects

Abstract

A template-guided, self-assembly patterning technique called discontinuous dewetting (DD) and liquid bridge transfer (LBT) was applied to successfully pattern single-walled carbon nanotubes (SWCNTs): the first 1D nanomaterials patterned using the technique. The technique could efficiently and simply pattern SWCNTs with 2.5-10 μm resolution using little energy, low temperature (≤90 °C), and low cost and is potentially compatible with roll-to-roll manufacturing. Many variables were investigated to determine successful patterning conditions. The SWCNT patterning technique demonstrates the potential to obtain the often mutually exclusive properties for SWCNT patterning of high resolution and fas..
