Designing MOF-Fiber Composites for Targeted Adsorptive Filtration Applications

Metal-organic frameworks (MOFs) are a class of porous materials that show great promise over a variety of applications including catalysis, separations, sensing, and storage. Even with the large number of MOFs synthesized to date along with an incredible degree of tunability, one challenge facing these materials is their incorporation into an engineering ready form. One promising technique for arranging MOFs is to imbed them in electrospun fibers. Techniques for optimizing the adsorptive properties of MOF impregnated fibers is to be discussed, including fiber crosslinking for applications in secondary growth and selective polymer removal from the fibers to improve the kinetic accessibility of MOFs in fibers.
