Chitosan, a naturally abundant and sustainable organic biopolymer, is the second most plentiful polysaccharide after cellulose and is useful for an extensive range of applications because of its abundance, low cost, excellent biodegradability, and renewability. MOFs are a novel class of crystalline hybrid porous materials composed of metal ions with bridged organic linkers. They have been applied to a wide range of applications such as wastewater treatment, gas sensors, catalysts, and drug delivery. In this study, MOFs (ZIF67 or CuBTC) are grown in situ on chitosan fibers (denoted as C-ZIF67 or C-CuBTC) for air filters and NO gas adsorption performance, particular matter filtration efficiency, and antibacterial properties of the fabricated materials against E. coli and S. epidermidis are investigated. The C-ZIF67 and C-CuBTC, derived from renewable resources, can be good alternatives for commercial synthetic air filters because they are biodegradable, cost-effective, and environment-friendly.
