受贻贝粘附蛋白中发现的DOPA的强粘附特性的启发，开发了使用天然来源的邻苯二酚和氨基酸的异分子着色用于可持续的纺织品着色。在室温下，通过用邻苯二酚和氨基酸的不同组合进行仿生着色，可以产生多种颜色。可以微调着色以在纺织材料上形成各种有吸引力的涂层。研究结果表明，一克材料可以用毫克的反应物染色，并且异分子着色可以赋予织物更宽的色域，从棕色到蓝色。儿茶酚-氨基酸颜料表现出良好的牢度性能，低毒性，和高度再现性的颜色在纺织品基材上。这种基于儿茶酚的着色也可以用更环保的冷轧堆方法实现，这进一步减少了水和能源的消耗。研究结果为纺织材料的着色开辟了一个新的可持续发展方向。
Inspired by the strong adhesion feature of DOPA discovered in mussel adhesive proteins, the heteromolecular pigmentations using naturally derived catechol and amino acids were developed for sustainable textile coloration. A diverse range of colour could be generated via biomimicking pigmentation with different combinations of catechol and amino acids at room temperature. The pigmentation could be finely tuned to form various attractive coating on textile materials. The findings showed that a gram of material could be dyed with milligrams of reactants, and the heteromolecular pigmentations could endow fabrics a wider colour gamut ranging from brown to blue. The catechol-amino acid pigments demonstrated good fastness properties, low toxicity, and highly reproducible colours on textile substrates. This catechol-based pigmentation could also be realized in a more environmentally friendly with cold pad-batch method, which further minimized both water and energy consumption. The results of the study open a novel sustainable direction for coloration of textile materials.
