Abstract

Freestanding boron nitride nanosheet (BNNS) films with designed structures are first fabricated by chemical vapor deposition (CVD) methods. As-prepared freestanding BNNS films exhibit outstanding hydrophobicity and lipophilicity properties. Such brilliant behaviors make them applicable in oil/water separation with very high fluxes up to 1 200 000 L m^-2 h^-1 bar^-1 and excellent separation efficiencies (ppm level in terms of the water content in the filtrate).

Keywords: boron nitride nanosheets; chemical vapor deposition; freestanding films; templates.
