Conventional textile dyeing relies on the use of dyes and pigments, which can cause severe environmental contamination and waste a large amount of water. Structural coloring is one of the effective ways to achieve environmentally friendly coloring of textiles. In this work, three plant polyphenols with the same o-benzenetriol structure (tannic acid (TA), gallic acid (GA), and tea polyphenol (TP)) were selected as raw materials. Three plant polyphenols can quickly form nanofilms at the gas-liquid interface through a Schiff base reaction with polyethyleneimine (PEI) under mildly alkaline conditions, which were deposited to the surface of silk fabric, allowing precise control over the thickness of film by adjusting the time, resulting in various structurally colored silk fabric. This method for creating structural colors is not substrate-specific and enables the quick production of structural colors on various textile substrates. Furthermore, the structural color silk fabric based on plant polyphenol has antibacterial performance. This textile coloring method is simple, cost-effective and environmentally friendly, providing a new approach to eco-friendly textile dyeing.
传统的纺织品染色依赖于染料和颜料的使用，这可能会导致严重的环境污染和大量的水浪费。结构色是实现纺织品环保染色的有效方法之一。在这项工作中，选择了三种具有相同邻苯三酚结构的植物多酚（单宁酸（TA）、没食子酸（GA）和茶多酚（TP））作为原料。在温和的碱性条件下，三种植物多酚可以通过与聚乙烯亚胺（PEI）的席夫碱反应在气液界面快速形成纳米薄膜，然后沉积到丝绸织物的表面，通过调整时间可以精确控制薄膜的厚度，从而在丝绸织物上产生各种结构色。这种产生结构色的方法不具有基材特异性，可以在各种纺织品基材上快速生产结构色。此外，基于植物多酚的结构色丝绸织物具有抗菌性能。这种基于植物多酚的结构色丝绸织物具有抗菌性能。这种纺织品染色方法简单、经济高效且环保，为环保型纺织品染色提供了新途径。
