摘要
为开发无机/聚合物复合微球在纺织品结构色上的应用,在制备粒径可控、单分散性优良的二氧化硅/聚甲基丙烯酸甲酯(SiO_2/PMMA)微球基础上,通过垂直沉积自组装法,在涤纶织物表面构建有序的SiO_2/PMMA光子晶体结构。应用场发射扫描电子显微镜(FESEM)、三维视频显微镜和多角度分光光度仪分别表征了涤纶织物表面SiO_2/PMMA光子晶体的排列及结构生色效果。研究结果表明:涤纶织物表面的SiO_2/PMMA光子晶体呈现三维有序的非密堆积面心立方结构;结构色鲜艳明亮,随微球粒径的变化而变化;在不同观察角度下结构色呈现出不同的色相及色彩饱和度,具有明显的虹彩效应。
In order to develop the structural coloration application of inorganic / polymer composite microspheres in textiles, on the basis of the preparation of SiO_2/ polymethylmethacrylate（ PMMA）microspheres with good monodispersity and controllable particle size,the ordered array of SiO_2/ PMMA photonic crystals were fabricated by vertical deposition self-assembly on the surface of polyester fabrics.FESEM, 3-D video microscope and multi-angle spectrophotometer were applied to observe the arrangements and characterize the structural colors of photonic crystals. The results indicated that the SiO_2/ PMMA photonic crystals on the surface of polyester fabrics present three-dimensional orderly nonclose packed face-centered cubic structure,displaying bright structural colors,and changed with the particle sizes. Observed from different view angles,SiO_2/ PMMA photonic crystals present different hues and color saturation degrees,indicating strong iridescent phenomena on the polyester fabrics.
