Abstract
A variety of amphiphobic porous materials are provided. The materials can include a variety of porous frameworks that have an outer surface functionalized by a plurality of perfluoroalkyl moieties. By careful selection of appropriate perfluoralkyl moieties, hydrophobic properties can be imparted to the exterior surface of the porous materials without significantly impacting the wetting properties of the porous interior. This can be used to create a variety of highly amphiphobic porous materials. Methods of making and using the amphiphobic porous materials are also provided.
Claims16
An amphiphobic porous material comprising either:
- i) (a) a porous framework comprising a metal organic framework, wherein the metal organic framework comprises a plurality of ligands having a structure according to one of the following formulas
- where
- represents a bond to a metal atom, and where each occurrence of R1 is either H, alkyl, alkenyl, perfluoroalkyl, partially fluorinated alkyl, perfluorothioalkyl, or partially fluorinated thioalkyl so long as at least some of the R1 comprise a perfluoroalkyl, partially fluorinated alkyl, perfluorothioalkyl, or partially fluorinated thioalkyl;
- and
- (b) an outer surface of the porous framework, wherein the perfluoroalkyl, partially fluorinated alkyl, perfluorothioalkyl, or partially fluorinated thioalkyl are located on the outer surface;
- or
- ii) a porous framework having an outer surface, the outer surface comprising a plurality of perfluoroalkyl moieties covalently attached to the outer surface.
An amphiphobic porous material comprising a porous framework that is a metal organic framework comprising a plurality of metal atoms and a plurality of organic ligands coordinating the metal atoms to form the porous framework, the porous framework having an outer surface, the outer surface comprising a plurality of perfluoroalkyl moieties covalently attached to the outer surface.
