What do solar cells, printed circuit boards, microprocessors, and LED displays have in common? They are essential to 21st-century life, and they are all limited to flat geometries by the use of spin coating during manufacturing. My research aims to develop a model for spin coating on curved surfaces, and use this to determine an optimal control strategy for the process. I will talk about how to model thin film flows on moving curved surfaces, the work we have done so far to adapt established coating techniques to curved surfaces, and the next steps to develop a novel multi-axis spin coating system.
