摘要：采用溶胶-凝胶法制备了二氧化硅（SiO 2 ）微球，并利用聚多巴胺（PDA）作为黑色吸光物质制备了 SiO 2 @PDA
微球；利用重力沉积法将 SiO 2 @PDA 微球沉积到白色涤纶织物表面，通过添加自制结构色粘合剂聚（甲基丙烯
酸缩水甘油酯-co-丙烯酸六氟丁酯）-g-聚乙二醇甲基丙烯酸酯〔P(GMA-co-FHBMA)-g-PEGMA〕以制备高牢度
结构色织物。采用马尔文高灵敏纳米粒度分析仪、SEM、测色仪、测量显微镜对 SiO 2 微球、SiO 2 @PDA 微球和
结构色织物进行了表征，探究了多巴胺用量与 SiO 2 @PDA 微球的粒径、形貌及织物结构色的关系；考察了粘合
剂用量对结构色牢度和色彩的影响。结果表明，制备的 SiO 2 微球粒径均匀、单分散性较好；随着多巴胺用量的
增多，制备的 SiO 2 @PDA 微球粒径增大，织物结构色红移；但多巴胺用量过多会使微球形貌粗糙，降低微球的
粒径均匀性、单分散性及结构色的亮度；P(GMA-co-FHBMA)-g-PEGMA 的加入可以抑制结构色开裂，提升牢度。

Abstract: SiO 2 microspheres were prepared by sol-gel method. Then, polydopamine (PDA) was used as
black light absorbing material to prepare SiO 2@PDA microspheres. Finally, structural color fabrics with
high colorfastness were prepared by gravity deposition method using SiO 2@PDA microspheres and our
own synthetic adhesive, poly(glycidyl methacrylate-co-hexafluorobutyl acrylat)-g-polyethylene glycol
methacrylate 〔P(GMA-co-FHBMA)-g-PEGMA〕. The SiO 2 microspheres, SiO 2@PDA microspheres and
structural color fabrics were characterized by Malvern high sensitive nano particle size analyzer, SEM,
colorimeter and measuring microscope. The relationship between amount of dopamine and particle size and
morphology of SiO 2@PDA microspheres, and structural color of fabric was investigated. The effect of
adhesive dosage on the fastness and colouration of structural color fabrics was studied. The results show
that the prepared SiO 2 microspheres have uniform particle size and good monodispersity. With the
increasing of dopamine content, the particle size of SiO 2@PDA microspheres increase, and the structural
color of fabric shows a red shift. However, excessive addition of dopamine can make the microspheres
rough, reduce the particle size uniformity and monodispersity of microspheres, and decrease the brightness
of structural color. The addition of P(GMA-co-FHBMA)-g-PEGMA can inhibit the crack of structural color
and improve the fastness.
