We study the fabrication of uniformly thick films on cylinders by dip-coating with oscillation. In conventional dip-coating, whose physics was first investigated by Landau, Levich, and Derjaguin, a fast process generates a coating thickness gradient while a slow process limits the film thickness and is time-consuming. A new coating method of thick films was recently proposed, which involves dipping a solid substrate in a bi-layer liquid bath with neutral buoyancy and applying oscillation. In this study, we first experimentally and theoretically find how the film thickness profile is determined in the uniaxial coating. Then, we find the condition to achieve uniform thickness distribution along the circumferential direction in the biaxial coating. Applications of our results are not limited to areas where coating is widely used, such as solar cells or flexible displays; it can be used in the medical industry for efficiently fabricating functional catheters and vascular replicas.
