The structural coloration of a chitosan-coated woven cotton fabric obtained by glutaraldehyde-stabilized deposition of electrostatic self-assembled monodisperse and spherically uniform (250 nm) poly (styrene-methyl methacrylate-acrylic acid) photonic crystal nanospheres (P(St-MMA-AA)) was investigated. Bright iridescent coatings displaying different colors in function of the viewing angle were obtained. The SEM, diffuse reflectance spectroscopy, TGA, DSC and FTIR analyses confirm the presence of structural color and the glutaraldehyde and chitosan ability to provide durable chemical bonding between cotton fabric and photonic crystal (PCs) coating with the highest degradation temperature and the lowest enthalpy. The coatings are characterized by a mixture of face-centered cubic and hexagonal close-packed arrays alternating random packing regions. For the first time a cost-efficient structural coloration with high washing and light fastness using self-assembled P(St-MMA-AA) photonic crystals was successfully developed onto woven cotton fabric using chitosan and/or glutaraldehyde as stabilizing agent opening new strategies for the development of dye-free coloration of textiles.
采用戊二醛稳定的静电自组装单分散、球形均一（250nm）的聚（苯乙烯-甲基丙烯酸甲酯-丙烯酸）光子晶体纳米球（P（St-MMA-AA））沉积，研究了壳聚糖涂层机织棉织物的结构色。得到了具有不同颜色的明亮的虹彩涂层，这些颜色随着观察角度的变化而变化。SEM、漫反射光谱、TGA、DSC 和 FTIR 分析证实了结构色的存在，以及戊二醛和壳聚糖在棉织物和光子晶体（PC）涂层之间提供持久化学键的能力，其具有最高的降解温度和最低的焓。涂层的特征是面心立方和六方密堆积阵列交替随机堆积区域的混合物。首次成功地在机织棉织物上使用壳聚糖和/或戊二醛作为稳定剂，用自组装的 P（St-MMA-AA）光子晶体实现了具有高耐洗性和耐光性的低成本结构着色，为无染料纺织品着色开辟了新的策略。
