光子结构材料引起了人们的广泛兴趣，并且在过去几年中在图像显示、传感和防伪材料方面得到了大力发展。它们的“智能”源于它们对环境、压力或外部场变化的颜色响应。在这里，我们介绍了一种新颖的隐形光子系统，通过简单地拉伸或浸入溶剂中即可显示加密的图像或字符。这种有趣的光子材料由规则排列的核壳颗粒组成，这些颗粒通过紫外线照射选择性交联，与未交联区域相比，产生不同的应变响应。当循环应变和释放应变时，图像可逆地出现和消失。与其他类型的光子凝胶相比，这种软聚合物蛋白石系统的独特优势在于，它可以批量生产，可以剧烈变形以实现强烈的颜色变化，并且由于它是光子橡胶系统，因此不存在溶剂蒸发问题。我们展示了潜在的应用以及简单且可扩展的制造过程，这对于用户的使用至关重要。我们的工作加深了对这种基于核壳纳米球的橡胶光子系统的理解。
Photonic structural materials have received intensive interest and have been strongly developed over the past few years for image displays, sensing, and anticounterfeit materials. Their “smartness” arises from their color responsivity to changes of environment, strain, or external fields. Here, we introduce a novel invisible photonic system that reveals encrypted images or characters by simply stretching, or immersing in solvents. This type of intriguing photonic material is composed of regularly arranged core–shell particles that are selectively cross-linked by UV irradiation, giving different strain response compared to un-cross-linked regions. The images reversibly appear and disappear when cycling the strain and releasing it. The unique advantages of this soft polymer opal system compared with other types of photonic gels are that it can be produced in roll to roll quantities, can be vigorously deformed to achieve strong color changes, and has no solvent evaporation issues because it is a photonic rubber system. We demonstrate potential applications together with a fabrication procedure which is straightforward and scalable, vital for user take-up. Our work deepens understanding of this rubbery photonic system based on core–shell nanospheres.
