Patent number: 11519148Abstract: A water-oil separation device uses a difference in density between water and oil. The water-oil separation device can easily and quickly separate oil by using a polymer film floating at interface between water and oil. The water-oil separation device easily and quickly collects oil of various viscosities with a simple structure by using differences in density between materials without using a conventional lyophilic/lyophobic film, thus solving the drawbacks of conventional filter-based and adsorption-based methods, and enabling quick and effective responses to actual oil spill situations.Type: GrantFiled: May 19, 2020Date of Patent: December 6, 2022Assignee: SEOUL NATIONAL UNIVERSITY R&DB FOUNDATIONInventors: Yong Hyup Kim, Youn Jeong Choe
