摘要

可重写纸由于具有促进社会可持续发展的潜在可能性，在环境友好型信息传播领域引起了广泛的研究关注。传统的有机染料基可重写纸可能会造成排放污染问题。为了解决这一问题，本研究通过在聚甲基丙烯酸甲酯基质中原位生长高度分散的cu掺杂wo3纳米颗粒，提出了一种柔性无机光致变色膜。基于w6 +和w5 +之间的氧化还原过程，制备的膜在紫外交替照射/加热下可重复显着变色200次以上。本文给出了可重写纸和加密算法的概念证明。研究结果对新型可重写彩色纸的设计和制造具有重要意义。

Inkless Rewritable Paper Enabled by a Scalable Photochromic Membrane

Rewritable paper has attracted wide research attention in the field of environment-friendly information transmission owing to its potential possibility to promote a sustainable society development. Traditional organic dye-based rewritable paper may cause emission of pollution problems. To solve this problem, this study presents a flexible inorganic photochromic membrane by in situ growth of highly dispersed Cu-doped WO 3 nanoparticles in a polymethyl methacrylate matrix. Obvious discoloration of as-prepared membrane can be repeated more than 200 times under alternating UV irradiation/heating based on an oxidation-reduction process between W 6+ and W 5+ . The proof of concept for rewritable paper and encryption algorithm is demonstrated herein. The results of this study are of great significance for the design and fabrication of novel-type rewritable colorful paper.
