摘要： A variety of superhyrdophobic porous materials are provided including a covalent organic framework having a plurality of perfluoroalkyl or perfluorheteroalkyl moieties covalently attached thereto. The materials can include a polymeric foam matrix made of a three-dimensional network of polymer fibers, and the covalent organic framework can be made encasing at least a portion of the polymer fibers. The covalent organic framework can be intertwined within the polymeric foam matrix such that the covalent organic framework encasing the portion of the polymer fibers is stable to mechanical compression of the polymeric foam matrix. Surfaces and other articles are provided including the superhyrdophobic porous materials are also provided, as are methods of making the superhyrdophobic porous materials, and methods of use for oil recovery among other things.

摘要： Compositions are provided for efficient uranium extraction, for example from wastewater, seawater, or other water sources. The compositions can include a functionalized porous organic polymer functionalized with one or more uranium binding moieties, e.g. having a plurality of amidoxime or amidrazone groups covalently attached thereto. The compositions can include covalent organic frameworks, porous aromatic frameworks, and various porous organic polymers, especially those having a hierarchical pore size distribution over a range of pore sizes. The compositions can have functional groups such as amidoxime or an amidrazone covalently attached thereto. The hierarchical pore size distribution can be determined based upon at least 60% of the pore sizes in the range of pore sizes having a pore volume of at least 0.01 cm3 g−1 in the pore size distribution at 77 K. Methods of making the compositions and methods of using the compositions are also provided.

摘要： 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.
