用于选择性地分离水和油的超亲水性过滤结构

Superhydrophilic filter structure for selectively separating water and oil

Abstract

Provided is a filter structure for effectively separating water and oil using wettability properties. The filter structure comprises: a first filter layer having a plurality of openings; and a second filter layer having a plurality of openings and overlapping the first filter layer while being spaced apart from the first filter layer. The surfaces of the first filter layer and second filter layer have a first fine microscale concavo-convex structure and a second fine nanoscale concavo-convex structure, thus achieving superhydrophilic properties and selectively letting the water from among the water and oil pass through.
提供一种用于使用润湿性性质有效地分离水和油的过滤结构。所述过滤结构包括:第一过滤层,其具有多个开口;和第二过滤层,其具有多个开口并且当与所述第一过滤层隔开时,重叠所述第一过滤层。所述第一过滤层和所述第二过滤层的表面具有第一细小的微米尺度凸-凹结构和第二细小的纳米尺度凸-凹结构,因此实现超亲水性质并且选择性地使来自水和油中的水穿过。
