Abstract
The disclosure relates to compositions containing alumina nanoparticles. Each alumina nanoparticle is covalently bonded to polyurethane and two different functional groups. One of the functional groups contains a fluorocarbon. The other functional group is capable of undergoing protonation. The wettability of the compositions can be altered by changes in pH. The disclosure also provides methods for synthesizing the compositions and using the compositions in oil-water separation applications.
