We show that during the spin coating, the thinning of the film is governed by the balance of viscous and centrifugal forces. We demonstrate that the method enables us to reach uniform micrometre-scale films on the tube walls. Finally, we discuss potential applications with curable polymers that enable precise control of film geometry and wettability.<\/p>\n\n\n\n<p>See paper:   <a data-type=\"URL\" data-id=\"http:\/\/thales.mit.edu\/bush\/wp-content\/uploads\/2021\/03\/Primkulov-JFM2020.pdf\" href=\"http:\/\/thales.mit.edu\/bush\/wp-content\/uploads\/2021\/03\/Primkulov-JFM2020.pdf\">Primkulov, Pahlavan, Bourouiba, Bush &amp; Juanes, JFM  (2020<\/a>).<\/p>\n<\/div><\/div>\n","protected":false},"excerpt":{"rendered":"","protected":false},"author":5,"featured_media":4424,"comment_status":"closed","ping_status":"closed","sticky":false,"template":"","format":"standard","meta":{"footnotes":""},"categories":[6],"tags":[],"class_list":["post-4422","post","type-post","status-publish","format-standard","has-post-thumbnail","hentry","category-interfacial-flows","entry"],"yoast_head":"<!-- This site is optimized with the Yoast SEO plugin v16.3 - https:\/\/yoast.com\/wordpress\/plugins\/seo\/ -->\n<title>Spin coating of capillary tubes - John W.
