As environmental problems increase, there is an urgent demand for new eco-friendly materials. Natural rubber latex (NRL) is a natural material extracted from rubber trees. But its dyeing process with chemical dyes might result in contamination and environmental degradation. Here, NRL is composited with a photonic crystal (PhC) structure by spin coating for the first time. The polymethyl methacrylate (PMMA) photonic nanostructure has been embedded into NRL to give it colors and provide it with optical functionalities. Colors of the composite could be designed and controlled by the sizes of the nanocolloids from 180 nm to 295 nm. The colors have strong stability under external stretching. The 3D natural rubber latex photonic crystal (NRLPC) is used as a responsive material to detect volatile organic compounds (VOCs) including formaldehyde, acetone, toluene, xylene and styrene. With its visual color appearance, biocompatibility and flexibility, NRLPC has promising potential in various sensing applications.
随着环境问题的增加，对新型环保材料的需求日益迫切。天然胶乳（NRL）是从橡胶树中提取的天然材料。但其用化学染料进行染色的过程可能会导致污染和环境退化。在这里，首次通过旋涂法将 NRL 与光子晶体（PhC）结构复合。将聚甲基丙烯酸甲酯（PMMA）光子纳米结构嵌入 NRL 中，赋予其颜色并提供光学功能。复合材料的颜色可以通过尺寸为 180nm 至 295nm 的纳米胶体来设计和控制。在外部拉伸下，颜色具有很强的稳定性。3D 天然胶乳光子晶体（NRLPC）可用作响应材料来检测包括甲醛、丙酮、甲苯、二甲苯和苯乙烯在内的挥发性有机化合物（VOCs）。由于其具有直观的颜色外观、生物相容性和柔韧性，NRLPC 在各种传感应用中具有广阔的应用前景。
