Fabrication of Superhydrophobic Polycaprolactone Foam via Phase Separation and Silica Modification for Oil–Water Separation

Abstract

Front Cover: In article 2300436, Yamin Pan, Xianhu Liu, and co-workers fabricate a superhydrophobic PCL 3D porous foam via thermally induced nonsolvent induced phase separation with additional extra water. After modification with silica nanoparticles, the foam achieves a water contact angle of 151.56°. Based on the invasion pressure theory, the foam could selectively adsorb or filter oil from water with high efficiency and flux.
