Abstract
A method of making a metal organic framework (MOF)-polymer composite material includes forming a homogeneous solution comprising a solvent, a metal salt, a polymer which is soluble in the solvent, and a reactant which can be synthesized to provide an organic linker during formation of a MOF structure, synthesizing the homogeneous solution to crystallize a MOF structure in the homogenous solution to yield the MOF structure distributed in a remainder solution, applying an antisolvent to the remainder solution with the MOF structure distributed in the remainder solution to form a polymer-rich phase, where the MOF structure is integrated into the polymer matrix during forming of the polymer matrix to produce a MOF-polymer composite material. The MOF-polymer composite material can be formed on a substrate to produce a MOF structured object, which can be a membrane, film, or other object.
