摘要

我们开发了一种新型复合光刻胶，由丙烯酸酯和羧基官能化多壁碳纳米管（MWNTs-COOH）制成，用于利用 STED 启发的光刻技术制造亚衍射尺寸的聚合物纳米线。分散在高交联丙烯酸酯单体中的 MWNTs-COOH 可降低抑制激光功率，从而改善光刻效果。使用 MWNTs-COOH 后，抑制激光功率从 5 mW 降至 3 mW，而可实现的最小特征尺寸从 121 nm 增至 48 nm。这种创新方法为微机电系统（MEMS）和纳米机电系统（NEMS）领域基于亚衍射 MWCNTs/聚合物复合材料的设备开发带来了巨大前景。

Novel carboxylic-MWCNTs photoresist for fabricating sub-diffraction polymer nanowires via STED lithography

A novel composite photoresist, derived from acrylates and carboxylic-functionalized multi-walled carbon nanotubes (MWNTs-COOH), has been developed for the fabrication of sub-diffraction-sized polymer nanowires using STED-inspired lithography. The MWNTs-COOH dispersed in highly cross-linking acrylate monomers benefits to a reduced inhibition laser power for improving lithography. With the MWNTs-COOH, the inhibition laser power is decreased from 5 mW to 3 mW, while the achievable minimum feature size is increased from 121 nm to 48 nm. This innovative approach holds significant promise for the development of sub-diffraction MWCNTs/polymer composite-based devices in the fields of Micro-Electro-Mechanical Systems (MEMS) and Nano-Electro-Mechanical Systems (NEMS).
