光子晶体在织物表面的色泽呈现

为探究结构色在织物显色方面的可行性以及织物组织结构对光子晶体结构色显色效果方面的影响，选用不同织物组织结构的黑色涤纶织物为基材，采用经典的Stöber 法制备高圆整度、单分散、粒径为150 ～300 nm 的Sio2微球，通过垂直沉积自组装法将微球组装在涤纶织物上得到显色效果较佳的光子晶体结构色。使用Lambda-35 紫外可见分光光度计进一步验证不同织物组织结构上光子晶体结构色的显色差异。结果表明：在相同自组装工艺条件下，织物组织结构不同造成的反射光强度差异将会影响光子晶体结构色的呈现；相比于平纹织物表面的结构色，缎纹织物的结构色亮度相对较暗。

Color development of photonic crystals on fabric surface

Polyester fabrics with different fabric structure were chosen as the base material toexplore the feasibility of structural color applying to textile coloration and the influences ofthe fabric structure on thestrutural color development of photonic crystals.Black polyester fabrics with different structure were chosen as the base material. SiO2 microspheres with high roundness, excellent monodispersity and diameter ranging from 150 nm to 300 nm, were prepared by Stöber method. The photonic crystals on polyester fabrics with ordered arrangement were fabricated by verticaldeposition self-assembly ofSiO2 microspheres, and exhibited brilliant structural colors .The Lambda-35 UV-VIA spectrometer were applied to confirm the color difference of structure color on polyester fabric with different fabric structure. It proved that under the same self-assembly process conditions, the reflection difference caused by different fabric surface structure influences the luster of structural color on the fabric . Compared with satin fabric, the luster of structural color on plain fabrics is more shiny.
