Amphiphilic Janus particles demonstrate unique assembly structures when dried on a hydrophilic substrate. Particle orientations are influenced by amphiphilicity and Janus balance. A three-stage model is developed to describe the process. Simulation further indicates the dominant force is capillary attraction due to the interface pinning at rough Janus boundaries.

两亲性Janus颗粒的干燥介导的取向和组装结构†

当在亲水性基材上干燥时，两亲性Janus颗粒表现出独特的组装结构。颗粒的取向受两亲性和Janus平衡的影响。开发了一个三阶段模型来描述该过程。模拟进一步表明，由于界面钉扎在粗糙的Janus边界上，主要作用力是毛细管吸引。
