Tuning surface properties of flexible materials enhances the versatility of existing materials, giving them new functions for applications in textiles, filtration, flexible electronics, and sensors. However, traditional surface modification methods are typically solvent-based, which limits the range of substrates that can be coated. In this work, we demonstrate the ability to use roll-to-roll processing to continuously modify the surface properties of large areas of flexible substrates using initiated chemical vapor deposition, which is an all-dry process. We designed and built a roll-to-roll module that can be used to uniformly coat 1500 cm² of chromatography paper in a single deposition. Rolls of paper were coated with a fluoropolymer and an ionizable polymer, and the coated paper was used for origami, nonstick surfaces, and paper-based microfluidic devices.

通过启动化学气相沉积对纤维素纸进行卷对卷表面改性

调整柔性材料的表面特性可增强现有材料的多功能性，使其在纺织品，过滤，柔性电子产品和传感器中具有新的功能。然而，传统的表面改性方法通常是基于溶剂的，这限制了可以涂覆的基材的范围。在这项工作中，我们展示了使用卷对卷处理功能通过发起化学气相沉积（这是一种全干过程）来连续修改大面积柔性基板表面性能的能力。我们设计并构建了卷对卷模块，可用于均匀涂布1500 cm ²单次沉积的色谱纸的数量。将纸卷涂上含氟聚合物和可电离的聚合物，并将涂好的纸用于折纸，不粘表面和纸基微流控设备。
