Graphene-Coated Poly(ethylene terephthalate) Nonwoven Hollow Tube for Continuous and Highly Effective Oil Collection from the Water Surface.

ABSTRACT: Graphene (GE) has attracted significant attention on account of its unique structure and superior performance, arousing a new research field for materials science. Herein, a novel GE-coated poly(ethylene terephthalate) nonwoven (PGNW) hollow tube (PGNW-T) was fabricated for continuous and highly effective oil collection from the water surface. The PGNW was prepared via a dip-spray coating method, which possessed superhydrophobicity-superoleophilicity and could absorb a variety of oils or organic solvents with the absorption capacity (Q) value of 18-34 times its own weight. Then, PGNW-T was obtained through winding the PGNW on the surface of a porous polypropylene hollow tube. As-prepared PGNW-T was competent for dynamic oil collection with high flux (18 799.94 L/m² h), ou
