Metal-organic framework (MOF) materials are a novel organic-nonorganic hybrid. Known for their high surface area and porosity, they have a wide range of applications in catalysis, gas separation, and drug delivery. In this study, MOF coated fabrics were developed either through simple dip or spray coating procedures, or through suspension processing after surface treatment with carboxymethylation. This research was first explored by coating cellulose-based substrates with several types of MOFs (e.g. ZIF-8, UIO-66, and HKUST-1). All were synthesized through solvothermal methods and attached via dipping or spraying, or through surface treatment and suspension processing. We have been able to confirm crystalline growth and MOF deposition to the substrate surface by observing expected morphologies for each MOF through scanning electron microscopy (SEM). MOF deposition has also been detected through area density changes, and confirmed through Brunauer – Emmett – Teller (BET) theory to give expected weighted averages of surface area between our highly porous MOFs and less-porous organic substrate. As of now, we can confirm that MOF loading is a function of passes if done through the multi-layer approach (dip or spray), and also solution concentration if done through suspension processing and surface treatment. We hope that we may obtain sufficient MOF coverage that will lead to filtering abilities comparable to standard filter masks (removing > 95% of particulate matter).
