论文摘要
基于聚合物纳米颗粒的自组装的合成蛋白石通常由于结构中的晶格缺陷过多而产生淡淡的/淡的结构颜色。在这里，我们通过蒸发自组装生产碳纳米管（CNT）掺入高质量的3D光子蛋白石（PC-CNT）。尽管CNT仅占制造的光子蛋白石的0.01％，但它们的受控掺入具有巨大的效果，可以将光子晶体的颜色从乳白色变为强烈的红色。微观研究表明，CNT掺入不影响光子晶体的晶格顺序。测试结构颜色的可调性作为入射角的函数，并根据Bragg-Snell定律进行了测试。此外，我们测试了光子蛋白石的机械色素传感，证明了它们作为视觉指标的潜力。这种可调的PC-CNT带来了许多可能性，包括应变感应或结构性医疗保健监测以及基本兴趣。
Synthetic opals, based on self-assembly of polymeric nanoparticles generally produces fainted/pale structural colors due to too many lattice flaws in the structures. Here we produces carbon nanotubes (CNTs) incorporated high quality 3D photonic opals (PC-CNT) by evaporative self-assembly. Although the CNTs make up only 0.01% of the fabricated photonic opal, their controlled incorporation has dramatic effect to change the color of the photonic crystals from milky white to intense red. Microscopic study suggest that CNT incorporation did not affect the lattice ordering of the photonic crystals. The tunability of structural colors, as a function of incident angle, were tested and varied against Bragg-Snell law. Furthermore, we tested mechanochromic sensing of the photonic opals, demonstrating their potential as visual indicators. This tunable PC-CNT brings many possibilities including strain sensing or structural health care monitoring, as well as being of fundamental interest.
