Polyacrylamide-Modified Polyester Fabric with Easy-Cleaning for Efficient Oil/Water Separation

With frequent oil spills occurring worldwide, oil/water separation technologies using materials with special surface wettability have attracted attention. In this study, a polyacrylamide hydrogel was synthesized and crosslinked onto polyester fabric via UV-initiated polymerization. The modified fabric showed superhydrophilicity and underwater superoleophobicity, which allowed water passage and inhibited oil permeation. Different oils (including...
