在这项工作中,我们介绍了一种简便的方法,用于制造良好的对齐的金纳米线在所需的微观结构相结合的剪切对齐的嵌段共聚物(BCP)的圆柱体与传统的光刻工艺。首先通过剪切排列圆柱形聚苯乙烯-嵌段-聚(2-乙烯基吡啶)薄膜,形成长程有序的排列线图案;然后,负载金,形成金属纳米线。我们直接在纳米片上采用光刻法,简化了许多制造步骤。此外,BCP组装和光刻的组合允许独立控制纳米图案和微图案,提供了增加纳米图案的多功能性的机会。在这项工作中,我们介绍了一种简便的方法,用于制造良好的对齐的金纳米线在所需的微观结构相结合的剪切对齐的嵌段共聚物(BCP)的圆柱体与传统的光刻工艺。
In this work, we introduce a facile method for fabricating well-aligned gold nanowires in a desired microstructure by combining the shear alignment of block copolymer (BCP) cylinders with a conventional lithography process. The aligned line patterns in a long-range order were firstly created with the shear alignment of cylinder-forming polystyrene-block-poly(2-vinylpyridine) thin films; then, gold was loaded to create metal nanowires. We directly employed photolithography on the nanopatterns, which simplified many fabrication steps. Furthermore, the combination of BCP assembly and photolithography allows for the independent control of nanopatterns and micropatterns, providing an opportunity to increase the nanopatterns' versatility. In this work, we introduce a facile method for fabricating well-aligned gold nanowires in a desired microstructure by combining the shear alignment of block copolymer (BCP) cylinders with a conventional lithography process.
