Abstract

We report a novel synthetic strategy to obtain photonic films through the self-assembly of polymeric core–shell particles onto functionalized carbon nanofibers (CNFs-F). Driven by the interfacial compatibility among the components, the particles adhere to the nanofibers’ surface promoting highly ordered latex particles (LP) that form opal films (OF) with minimal defects. In contrast, litmus films obtained from single core–shell latex particles (OF-L) show an arrangement in small domains randomly oriented. CNFs-F-based opal films emit a green coloration with an incidence angle of visible light (IAVL) of 90°. Meanwhile, a blue coloration is observed at an angle of 45°, an optical effect characteristic of green films, also called Ogreen.

功能化碳纳米纤维诱导聚合乳胶颗粒有序合成蛋白石薄膜
我们报道了一种新的合成策略,通过在功能化碳纳米纤维(CNFs-F)上自组装聚合核壳粒子来获得光子薄膜。在组分之间界面相容性的驱动下,颗粒粘附在纳米纤维表面,促进高度有序的乳胶颗粒(LP)形成缺陷最小的蛋白石膜(OF)。相比之下,由单核-壳乳胶颗粒(OF-L)获得的石蕊片显示出随机取向的小域排列。cnfs - f基蛋白石薄膜在可见光入射角(IAVL)为90°时发出绿色。同时,在45°角处观察到蓝色,这是绿色薄膜(也称为Ogreen)的光学效应特征。图形抽象
