Drying mediated orientation and assembly structure of amphiphilic Janus particles

Miller, Kyle; Tsyrenova, Ayuna; Anthony, Stephen M.; Qin, Shiyi; Yong, Xin; Jiang, Shan

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.
