摘要
采用无皂乳液聚合法,以苯乙烯(St)和丙烯酸羟乙酯(HEA)为共聚单体,过硫酸铵(APS)为引发剂制备P(St-HEA)胶体微球,然后以其为结构单元,应用垂直沉积法在棉织物上构建P(St-HEA)仿生光子晶体结构。利用马尔文动态粒度测试仪、场发射扫描电子显微镜(FESEM)和透射电子显微镜(TEM)测定和观察P(St-HEA)胶体微球的粒径、单分散性及形貌结构,利用FESEM观察棉织物上P(St-HEA)光子晶体的表面形貌,通过三维视频显微镜、紫外-可见分光光度仪和多角度分光光度仪表征P(St-HEA)光子晶体结构色的生色效果。研究结果表明:随St用量减少、HEA用量增加或APS用量增多,P(St-HEA)胶体微球粒径增大;微球分布均匀、球形度良好,呈现典型的软壳-硬核结构;棉织物表面P(St-HEA)光子晶体为三维面心立方结构,呈现出鲜艳明亮、色彩均匀且虹彩明显的仿生光子晶体结构色。
The P（St-HEA） colloidal microspheres were prepared by soap-free emulsion copolymerization,in which styrene（St）and hydroxyethyl acrylate（HEA）as monomers,and ammonium persulfate（APS）as an initiator.The structure of P（St-HEA）biomimetic photonic crystal on purecotton fabrics was fabricated by vertical deposition self-assembly with P（St-HEA）microspheres.The particle sizes and monodisperse properties and morphology structure of the prepared microsphereswere tested and observed by Malvin dynamic particle size tester,FESEM and TEM,respectively.The microstructure of P（St-HEA）photonic crystal on cotton fabrics was observed by FESEM.Moreover,the color effect,reflectivity and iridescent phenomenon of P（St-HEA）photonic crystal structure on cotton fabrics surface were observed and tested by 3 D Video microscope, UV-Vis spectrophotometer and Multi-angle spectrophotometer.The results showed that：with the decrease of St,increase of HEA or increase of APS,the particle sizes of P（St-HEA）colloidal microspheres monotonously increased.The prepared P（StHEA）colloid microspheres were well distributed and spherical,showing a typical hardcore-soft shell structure.The P（St-HEA）photonic crystal presents a three-dimensional face centered cubic（FCC）structure on cotton fabrics,in which the microspheres were arranged orderly.After the self-assembly,the cotton fabrics presented bright and uniform structural colors with distinct iridescent phenomenon.
