纳米尺度的表面结构可以赋予块体材料新的和令人兴奋的性能。疏水材料上的纳米级结构可以导致超疏水性和结构着色。我们提出了一个跨学科的实验，介绍了本科生纳米技术通过操纵超疏水性和结构着色的蓝色大闪蝶翅膀。使用清洁剂可以将机翼的表面从超疏水性改变为亲水性，而使用普通溶剂可以改变环境折射率并将相干散射光转移到更长的波长。超疏水性和折射率的改变是很容易观察到的使用Morpho menelaus和Morpho rhetenor蝴蝶：水珠和滚下未经处理的蝴蝶翅膀，而洗涤剂处理的翅膀被水弄湿，颜色从明亮的蓝色变成绿色。这个实验是一个有趣的和有影响力的介绍基本物理原理，...
Surface structures on the nanometer size scale can impart new and exciting properties to bulk materials. Nanoscopic structures on hydrophobic materials can result in superhydrophobicity and structural coloration. We present an interdisciplinary experiment that introduces undergraduate students to nanotechnology by manipulating the superhydrophobicity and structural coloration of blue Morpho butterfly wings. The use of detergents can change the surface of the wing from superhydrophobic to hydrophilic, while the use of common solvents can change the ambient index of refraction and shift coherently scattered light to longer wavelengths. Superhydrophobicity and alteration of the index of refraction are readily observable using Morpho menelaus and Morpho rhetenor butterflies: water beads up and rolls off untreated butterfly wings, while detergent-treated wings get wetted by water and change color from bright blue to green. This experiment is a fun and impactful introduction to fundamental physical principles i...
