摘　　要：针对碳纤维难着色的问题,提出利用结构生色实现碳纤维/涤纶混纺纱线的着色。以聚(苯乙烯-甲基丙烯酸)胶体微球为结构基元,利用浸渍提拉法在碳纤维/涤纶混纺纱线上构筑光子晶体生色结构。分析组装液质量分数和自组装温度对结构色的影响,探究胶体微球在纱线表面组装成光子晶体的过程,利用聚二甲基硅氧烷(PDMS)封装技术提升结构生色纱线的色彩耐久性。结果表明:当组装液质量分数为70%、自组装温度为40℃时,可以在纱线表面构筑得到结构色明亮的光子晶体;胶体微球在纱线表面的组装过程归纳为预备阶段、堆砌聚集和完备阶段;经PDMS封装后的结构生色纱线经历水洗摩擦后依旧保持原有的色彩鲜艳度。该研究可为实现彩色碳纤维制品的现代化生产和应用提供新的策略。Objective Carbon fiber is widely used in aerospace, infrastructure, military equipment, sports and other fields due to its excellent physical and chemical properties. However, the color of carbon fiber is much too limited to meet the needs of various possible applications. At present, the colored carbon fiber is obtained by modifying its surface and then coloring it with chemical colorants. Although colored carbon fiber can be prepared by this method, the excellent properties of carbon fiber are negatively affected to a certain extent because of the surface modification before coloration. New technologies suitable for coloring carbon fiber are needed. Method The coloring of carbon fiber was achieved through structural coloration. In this study, monodispersed poly(styrene-methacrylic acid)(P(St-MAA)) colloidal microspheres were prepared by soap-free emulsion polymerization, and were then used as building blocks to construct photonic crystal colored structures on carbon fiber/polyester blended yarns by a dip-coating method. Results When the mass fraction of P(St-MAA) colloidal microspheres assembly solution was 70% and the self-assembly temperature was 40 ℃, brighter structural colors can be fabricated on the surface of carbon fiber(Fig. 3 and Fig. 6). It is seen that the process of self-assembly of P(St-MAA) colloidal microspheres on the yarn surface to form photonic crystals can be briefly categorized into preparatory stage, stacking aggregation stage and completion stage, and the corresponding structural color is formed with a series of color shifts(Fig.8-10). The colors presented by the yarn of the structural colored carbon fiber/polyester blended yarn varied with different observation angles, exhibiting a significant iridescent effect(Fig.11). The polydimethylsiloxane(PDMS)-encapsulated structural colored carbon fiber/polyester blended yarn can still maintain the original structural colors after washing and rubbing tests, indicating its outstanding color durability, as indicated in Fig.13-14.
