Biodegradable highly nanostructured paper has received great interest in past years due to its excellent optical properties which facilitate its wide applications in green flexible electronics and devices. However, energy and/or time-consuming procedure during the process of fabricating most nanostructured transparent paper are presently the main obstacle to their scalable production. In this work, we demonstrated a novel nanostructured paper with dually high transparency (∼91%) and high haze (∼89%) that was directly fabricated from original paper with rapid ILs-polishing processes. The whole fabricating time only requires 10 min. Compared to the previously reported nanopaper made of the isolated cellulose nanofibers by pure mechanical and/or chemical approaches, this work presented herein is devoted to use green ILs to polish directly the micrometer-sized fibrous paper into the nanostructured paper. This new method brings a rapid fabrication of transparent nanostructured paper while also retaining dual intriguing properties both in optical transmittance and haze. This work is capable of fabricating next-generation flexible and highly transparent and haze paper by a high-speed roll-to-roll manufacturing process with a much lower cost.
在过去几年中，由于其出色的光学性能，可生物降解的高度纳米结构化纸张引起了极大的关注，这使其在绿色柔性电子和设备中得到了广泛的应用。然而，制造大多数纳米结构化透明纸的过程中能源和/或耗时的程序目前是大规模生产的主要障碍。在这项工作中，我们展示了一种新颖的纳米结构化纸张，其具有双重高透明度（约 91%）和高光雾度（约 89%），可通过原始纸张和快速离子液体抛光工艺直接制造。整个制造过程仅需要 10 分钟。与之前报道的由纯机械和/或化学方法制备的由孤立纤维素纳米纤维制成的纳米纸相比，本文工作致力于使用绿色离子液体直接将微米级纤维纸抛光成纳米结构化纸张。这种新方法可以在保留光学透过率和光雾度的双重有趣特性的同时，快速制造透明纳米结构化纸张。这项工作能够通过高速卷对卷制造工艺以更低的成本制造下一代柔性、高透明和高雾度纸张。
