| 目的 制备基于SiO2@CA微球的非晶结构色涂层，并得到调控结构色颜色的方法，作为功能包装或智能包装的潜在应用。方法 将咖啡酸(CA)与SiO2微球在CuCl2和NaBO3.4H2O的催化下产生活性氧(ROS)，使CA迅速氧化为具有强黏附性的聚咖啡酸(PCA)包覆SiO2微球，即SiO2@CA复合微球，然后将该复合微球与无水乙醇组成的悬浮液喷涂于亲水化的玻璃基片表面，从而制得非晶结构色涂层。采用FT-IR、XPS、TGA、SEM等对SiO2@CA复合微球及其结构色涂层进行表征，研究CA含量、CuCl2/CA的质量比和NaBO3.4H2O/CA的质量比对复合微球的形貌及结构色涂层光学性能的影响。结果 在CA质量分数为5%、CuCl2/CA的质量比为1∶2和NaBO3.4H2O/CA的质量比为6∶4的制备条件下可以得到适宜的SiO2@CA复合微球及结构色涂层。结论 采用CA可有效提高所制备非晶结构色涂层颜色的对比度，实现颜色调控。 |

| The work aims to prepare amorphous structured color coatings based on SiO2@CA microspheres and get the method of regulating the structured color as a potential application of functional packaging or smart packaging. Caffeic acid (CA) and SiO2 microspheres were catalyzed by CuCl2 and NaBO3-4H2O to generate reactive oxygen species (ROS), which rapidly oxidized CA to strongly adherent polycaffeic acid (PCA) coated SiO2 microspheres, thereby preparing SiO2@CA composite microspheres, and the suspension composed of the composite microspheres and anhydrous ethanol was sprayed on the surface of hydrophilized glass substrates to obtain amorphous structured color coating layer. The SiO2@CA composite microspheres and their structured color coatings were characterized by FT-IR, XPS, TGA and SEM, and the effects of CA content, mass ratio of CuCl2/CA and mass ratio of NaBO3-4H2O/CA on the morphology of the composite microspheres and the optical properties of the structured color coatings were investigated. Suitable SiO2@CA composite microspheres and structured color coatings could be obtained under the preparation conditions of 5% CA, mass ratio of CuCl2/CA as 1∶2 and mass ratio of NaBO3.4H2O/CA of 6∶4. CA could effectively improve the color contrast of the amorphous structured color coating and realize the color regulation. |
