Distinguished from the chromatic mechanism of dyes and pigments, structural color is derived from physical interactions of visible light with structures that are periodic at the scale of the wavelength of light. Using colloidal crystals with coloring functions for fabrics has resulted in significant improvements compared with chemical colors because the structural color from colloidal crystals bears many unique and fascinating optical properties, such as vivid iridescence and nonphotobleaching. However, the poor mechanical performance of the structural color films cannot meet actual requirements because of the weak point contact of colloidal crystal particles. Herein, we demonstrate in this study the patterning on voile fabrics with high mechanical strength on account of the periodic array lock effect of polymers, and multiple structural color output was simultaneously achieved by a simple two-phase self-assembly method for printing voile fabrics with 3D colloidal crystals. The colored voile fabrics exhibit high color saturation, good mechanical stability, and multiple-color patterns printable. In addition, colloidal crystals are promising potential substitutes for organic dyes and pigments because colloidal crystals are environmentally friendly.
与染料和颜料的颜色机制不同，结构色源于可见光与在光波长尺度上具有周期性的结构之间的物理相互作用。将具有着色功能的胶体晶体用于织物，与化学颜色相比，已经取得了显著的改进，因为胶体晶体的结构色具有许多独特而迷人的光学特性，例如鲜艳的虹彩和不褪色。然而，由于胶体晶体颗粒的弱点接触，结构色膜的机械性能较差，无法满足实际要求。在此，我们通过聚合物的周期性阵列锁定效应，在薄纱织物上进行了具有高机械强度的图案设计，并通过简单的两相自组装方法，同时实现了用于打印具有 3D 胶体晶体的薄纱织物的多重结构色输出。彩色薄纱织物具有高色彩饱和度、良好的机械稳定性和可打印的多种颜色图案。此外，由于胶体晶体环保，胶体晶体是有机染料和颜料的有前途的潜在替代品。
