Abstract
Hierarchical porous membranes suitable for use in oil/water separation processes are provided. The membranes described herein are particularly well suited for separating trace amounts of water (e.g., no greater than 3 wt % water content, no greater than 1 wt % water content, or 50-1000 ppm water) from oil. The membranes have a wide range of applications, including deep seep oil exploration, oil purification, and oil spill cleanup.
