Superhydrophobic and superlipophilic LDH flower balls/cellulose membranes for efficient oil–water separation

Abstract

In this work, superhydrophobic and lipophilic Ni-Al LDH/cellulose membranes with flower-like microscopic surface morphology were successfully prepared at low cost. The rough surface morphology was obtained by in situ growth...

“Two birds with one stone” strategy for oil/water separation based on Ni foams assembled using metal–organic frameworks

“…[6][7][8][9] Inspired by their magical and almighty nature, biomimetic superantiwetting/superwetting mesh materials have attracted wide attention as a solution. 10,11 At present, oil-water separation is mainly acquired by membrane materials with superhydrophobicity-superoleophilicity (SHB&SOL). [12][13][14][15][16] The use of membrane materials with superhydrophilicityunderwater superoleophobicity (SHL&UWSOB) is another shrewd decision, as demonstrated by the antiwetting behavior of the oil droplets on the lower side of lotus leaves or fish scales in water.…”
