Hongjun Yang and co‐workers fabricated a porous PLA membrane via phase separation by using water microdroplets produced from an ultrasonic atomizer as a coagulation bath. The porous membrane exhibits a unique S‐shaped structure, where edge‐on lamellae radiate from the nucleus. Dendritic fibrils appear stacked together and individual units are S‐shaped. Micropores are also visible between fibrils. The radial crystal grows from the core and spans several micrometers. A chain‐folding model is used to explain the lamellar curvature.
