Superhydrophobic functionalized cellulosic paper by copper hydroxide nanorods for oils purification

Abstract Oily water contamination has been sighted as one of the most global environmental pollution. Herein, copper hydroxide nanorods layer was constructed onto cellulosic filter paper surface cured with polydopamine, Ag nanoparticles, and Cu NPs through immersion method. This work has been aimed...
