Structural coloration as the most possible way to realize the ecofriendly dying process for textiles or fabrics has attracted significant attention in the past decades. However, photonic crystals (PCs) are a typical example of materials with structural color usually located on the surface of the fabrics or textiles, which make them not stable when rubbed, bent, or washed due to the weak interaction between the PC coatings and fabrics. Here, double networks were constructed between the PC coatings and the fabrics for the first time via a hydrogen bond by introducing tannic acid (TA) and dynamic cross-linking with 2-formylphenylboronic acid to increase the wash resistance of the structural colored fabrics. On modifying the monodispersed SiO nanoparticles, poly(dimethylsiloxane), and the fabrics, the interaction between the PC coatings and the fabrics increased by the formation of double networks. The structural color, wash, and rub resistance of the PC-coated fabrics were systematically studied. The obtained fabrics with the TA content at 0.030% (SiDT30) showed the best wash and rub resistance. The construction of double networks not only improved the wash and rub resistance of PCs but also retained the bright structural color of the PC coatings, facilitating the practical application of structural coloration in the textile industry.
结构色化为实现纺织品环保染色过程的最可能途径，在过去几十年中引起了广泛关注。然而，光子晶体（PCs）是具有结构色的典型材料，通常位于织物或纺织品的表面，由于 PC 涂层与织物之间的弱相互作用，使得它们在摩擦、弯曲或洗涤时不稳定。在这里，首次通过氢键将单宁酸（TA）和动态交联引入 2-甲酰基苯硼酸之间，在 PC 涂层和织物之间构建双网络，以提高结构色织物的耐洗性。通过对单分散二氧化硅纳米粒子、聚二甲基硅氧烷和织物进行修饰，通过形成双网络增加了 PC 涂层与织物之间的相互作用。系统研究了 PC 涂层织物的结构色、耐洗性和耐摩擦性。当 TA 含量为 0.030%（SiDT30）时，得到的织物具有最佳的耐洗性和耐摩擦性。双网络的构建不仅提高了 PCs 的耐洗性和耐摩擦性，而且保留了 PC 涂层的鲜艳结构色，为结构色在纺织工业中的实际应用提供了便利。
