摘要

本研究探讨了乳酸反应性和非乳酸反应性聚合物功能化棉织物的反应，重点是颜色和图案的变化。圆形样品与乳酸反应聚合物结合，用靛蓝三磺酸染色，随着乳酸浓度的增加，颜色明显从蓝色转变为无色。这种效果与聚合物中乳酸与硼酸基团结合引发的染料释放有关。相比之下，具有非响应性聚合物的样品显示最小的颜色变化。对照片的RGB分析显示，乳酸反应样品的r值发生了显著变化，表明可以通过简单的测量进行半定量乳酸检测。此外，面部模式样本可视化乳酸反应，将一张微笑的脸变成一张哭泣的脸，乳酸水平上升。在另一种阴离子染料酸红18中也观察到类似的结果。这些发现证明了设计可穿戴乳酸传感器的前景，该传感器可以实现简单、无负担的监测。

Pattern changes in cotton fabrics functionalized with lactate-responsive polymers

This study explored the responses of cotton fabrics functionalized with lactate-responsive and non-responsive polymers, focusing on color and pattern changes. Circular samples, conjugated with lactate-responsive polymers and stained with indigotrisulfonate, showed distinct color shifts from blue to colorless as lactate concentration increased. This effect was linked to dye release triggered by lactate binding to boronic acid groups in the polymer. In contrast, samples with non-responsive polymers displayed minimal color changes. RGB analysis of photographs revealed significant R-value shifts in lactate-responsive samples, suggesting potential for semi-quantitative lactate detection via simple measurements. Additionally, facial pattern samples visualized the lactate response, transforming a smiling face into a crying face with rising lactate levels. Similar results were observed with another anionic dye, Acid Red 18. These findings demonstrate the promise of designing wearable lactate sensors that enable easy, burden-free monitoring.

期刊介绍： Dyes and Pigments covers the scientific and technical aspects of the chemistry and physics of dyes, pigments and their intermediates. Emphasis is placed on the properties of the colouring matters themselves rather than on their applications or the system in which they may be applied. Thus the journal accepts research and review papers on the synthesis of dyes, pigments and intermediates, their physical or chemical properties, e.g. spectroscopic, surface, solution or solid state characteristics, the physical aspects of their preparation, e.g. precipitation, nucleation and growth, crystal formation, liquid crystalline characteristics, their photochemical, ecological or biological properties and the relationship between colour and chemical constitution. However, papers are considered which deal with the more fundamental aspects of colourant application and of the interactions of colourants with substrates or media. The journal will interest a wide variety of workers in a range of disciplines whose work involves dyes, pigments and their intermediates, and provides a platform for investigators with common interests but diverse fields of activity such as cosmetics, reprographics, dye and pigment synthesis, medical research, polymers, etc.
