蝴蝶翅膀鳞片的细微结构,会使光发生折射、漫反射和衍射等,从而产生各种颜色。这种“结构色”就是蝴蝶艳丽色彩的来源之一。日本国立材料科学研究所的科研人员受此启发,发明了一种可以变色的橡胶。他们在橡胶表面涂上一层纳米颗粒。随着橡胶被拉扯或折叠扭曲,颗粒的位置会发生改变,进而使橡胶呈现出不同的色彩。酷比看点让橡胶变色可不是单纯为了好看!这种变色橡胶至少有三大用途:制造儿童玩具或装饰 The fine structure of the butterfly wing scales causes light to refract, diffuse, and diffract, resulting in a variety of colors. This “structural color” is one of the sources of the bright colors of butterflies. Researchers at the National Institute of Materials Science in Japan were inspired to invent a rubber that could change color. They coated the rubber with a layer of nanoparticles. As the rubber is pulled or twisted, the position of the particles changes, which in turn gives the rubber a different color. It’s not just for the sake of cool look than to let the rubber change color! This color-changing rubber has at least three major uses: making children’s toys or decorations
