Rotating cylindrical stamp-based nanoimprint technique has many advantages, including the continuous fabrication of intriguing micro/nanostructures and rapid pattern transfer on a large scale. Despite these advantages, the previous nanoimprint lithography has rarely been used for producing sophisticated nanoscale patterns on a non-planar substrate that has many extended applications. Here, the simple integration of nanoimprinting process with a help of a transparent stamp wrapped on the cylindrical roll and UV optical source in the core to enable high-throughput pattern transfer, particularly on a fabric substrate is demonstrated. Moreover, as a functional resin material, this innovative strategy involves a synergistic approach on the synthesis of molecularly imprinted polymer, which are spatially organized free-standing perforated nanostructures such as nano/microscale lines, posts, and holes patterns on various woven or nonwoven blank substrates. The proposed materials can serve as a self-encoded filtration medium for selective separation of formaldehyde molecules. It is envisioned that the combinatorial fabrication process and attractive material paves the way for designing next-generation separation systems in use to capture industrial or household toxic substances.
旋转圆柱压印基纳米压印技术具有许多优点，包括连续制造有趣的微/纳米结构和大规模快速图案转移。尽管有这些优点，但以前的纳米压印光刻技术很少用于在具有许多扩展应用的非平面衬底上制造复杂的纳米级图案。在这里，通过在圆柱形辊上包裹透明压印模板和核心中的 UV 光学源，简单地集成纳米压印工艺，实现了高通量图案转移，特别是在织物衬底上。此外，作为一种功能树脂材料，这种创新策略涉及分子印迹聚合物的协同合成，该聚合物是空间组织的独立穿孔纳米结构，例如各种机织或非织造坯布衬底上的纳米/微尺度线、柱和孔图案。所提出的材料可用作选择性分离甲醛分子的自编码过滤介质。可以预见，组合制造工艺和有吸引力的材料为设计下一代分离系统铺平了道路，这些系统用于捕获工业或家庭有毒物质。
