高效和可持续的功能化是实现木质纤维素纳米纸（LNP）高价值和规模化应用的关键问题之一，可再生纳米材料具有独特的技术吸引力。与其在植物细胞壁中的作用类似，木质素是 LNP 基质中的重要功能成分。然而，其固有的光吸收特性使得 LNP 不适合光学工程应用。在这里，开发了一种高效、可控且环保的木质素改性策略，利用 H 2 O 2的有益协同效应来调节 LNP 的光学性能。和紫外光选择性地消除木质素发色团。由于木质素改性后木质素的芳香骨架结构保存完好，所获得的木质素改性LNP不仅具有高可见光透射率（89%），而且具有高雾度（90%）和优异的紫外线屏蔽能力。此外，通过选择性木质素改性方法，可以在热压诱导的致密 LNP 上轻松实现图案化，这赋予 LNP 有趣的光学可设计性。受益于用于纳米纸基质的木质素组分的多功能性，图案化 LNP 表现出出色的水和热稳定性、阻隔性、耐久性和生物降解性，这对实际应用具有重要意义。
