Abstract

Abstract: 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. Abstract : Simple integration of UV‐optical engine for the cylinder roll‐assisted nanoimprinting process is presented to enable high‐throughput pattern transfer, especially on fabric substrates. This approach involves the use of molecularly imprinted polymers to spatially construct free‐standing perforated micro/nanostructures with functions that can serve as a self‐encoding filtration medium for the selective separation of formaldehyde molecules.
