摘要：
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. © 2021, Periodical Agency of Journal of Textile Research.
