Abstract (en)
[origin: WO2022207613A2] Porous liquid-filtering membranes (101, 201, 401, 501, 601) having a repeatable distribution of pores (105, 205, 405, 505, 605) of a small dimension are provided, as well as pillar templates (200, 400, 500, 600) that are used to produce such liquid filtering membranes (101, 201, 401, 501, 601). Also disclosed are methods of making and using the pillar templates (200, 400, 500, 600) to make porous liquid filtering membranes (101, 201, 401, 501, 601).
