喷涂胶体水溶液绿色制备结构色织物

Green synthesis of structural colored fabrics by spraying aqueous colloidal solutions

以SiO_(2)胶体水溶液作为原料,一步喷涂制得色彩饱和且均匀的SiO_(2)/PET结构色织物.通过优化热处理温度、溶液pH值、引入少量乙醇,有效改善了结构色的亮度和均匀性.该方法采用水作为主溶剂,降低了环境污染和生产成本,必将促进结构色织物的推广与应用.

This study developed a one-step spraying method using an aqueous solution of SiO_(2)particles to prepare SiO_(2)/PET fabrics with saturated and uniform structural colors.The color brightness and uniformity were significantly improved by optimizing the treatment temperature,pH of the colloidal solution,and by introducing a small amount of ethanol.This method would promote the applications of structural colored fabrics because using water would reduce both environmental pollution and production cost.
