自然界中的许多生物，如蝴蝶和孔雀，呈现出独特的明亮颜色，被称为“结构色”，这是光与它们表面的周期性纳米结构相互作用的结果。然而，模仿自然界中发现的这种纳米结构需要最先进的纳米制造技术，这些技术缓慢、昂贵且不可扩展。在此，我们展示了在几秒钟内多种结构颜色的高分辨率图案，基于使用单一材料和无掩模光刻系统的连续调谐和固定颜色。我们发明了一种叫做“M-Ink”的材料，它的颜色可以通过磁性改变纳米结构的周期性来调节，并且可以通过光化学固定这些结构在聚合物网络中来固定。我们还演示了实现结构彩色印刷的柔性光子晶体。所提出的简单、可控和可扩展的结构彩色印刷方案可能对一般消费品的彩色生产产生重大影响。
Many creatures in nature, such as butterflies and peacocks, display unique brilliant colours, known as 'structural colours', which result from the interaction of light with periodic nanostructures on their surfaces. Mimicking such nanostructures found in nature, however, requires state-of-the-art nanofabrication techniques that are slow, expensive and not scalable. Herein, we demonstrate high-resolution patterning of multiple structural colours within seconds, based on successive tuning and fixing of colour using a single material along with a maskless lithography system. We have invented a material called 'M-Ink', the colour of which is tunable by magnetically changing the periodicity of the nanostructure and fixable by photochemically immobilizing those structures in a polymer network. We also demonstrate a flexible photonic crystal for the realization of structural colour printing. The simple, controllable and scalable structural colour printing scheme presented may have a significant impact on colour production for general consumer goods.
