Abstract

Stable Zr-UiO-67 is prepared by introducing a fluorine-containing layer on its surface through a polymeric network assisted post-synthetic modification (PSM) strategy. The stability of the MOFs in acidic, alkaline and saline environments is improved because of the existence of a protective layer. The MOFs are superlyophobic towards liquids with a surface tension threshold of over 48 mN m^-1, making them a potential choice for separating various liquid-liquid mixtures and emulsions.
