摘　　要：为提高纺织品结构生色光子晶体的色彩饱和度,通过静电吸附将黑色活性染料引入带正电聚苯乙烯(PSt)胶体微球表面,制备了一种外表面吸附染料型PSt结构基元(活性染料/PSt微球),采用数码喷印方式在桑蚕丝织物上构建结构生色光子晶体。研究了染料在PSt胶体微球表面的吸附条件和吸附模型,对活性染料/PSt微球的结构形貌及所得光子晶体的排列和结构生色效果进行表征。结果表明:PSt微球表面染料的吸附量随时间、温度和染料用量的增大而增大;该吸附模型符合Langmuir型;活性染料/PSt微球具有典型的核壳结构,微球粒径较吸附前略有增大;白色蚕丝织物表面所构建的活性染料/PSt光子晶体生色结构,微球排列规整有序,呈现鲜艳明亮的结构色。In order to improve the color saturation of structural chromogenic photonic crystals on textiles,black reactive dye was introduced onto the surface of positively charged polystyrene(PSt)colloidal microspheres through electrostatic adsorption,resulting in the formation of an external surface absorbable dye PSt structural element(reactive dye/PSt microspheres)for structural coloring.The adsorption process and the modeling of dyes on the surface of PSt colloidal microspheres were studied,the morphology of reactive dye/PSt microspheres was observed,and the arrangement and structural color effects of prepared photonic crystals were characterized.The research results led to the following findings:the adsorption capacity of dyes on PSt microspheres increases with the increase of time,temperature and dye dosage;the adsorption model conforms to Langmuir type;the reactive dye/PSt microspheres have typical core-shell structure,and the particle size of microspheres slightly increases compared with that before adsorption;and the prepared reactive dye/PSt photonic crystals on white silk fabrics present regular arrangement and bright structural colors.
