(744d) Rapid Synthesized and Effective Metal-Organic Frameworks (MOFs) Based Filter

Due to the COVID-19, many people have suffered from the shortage of personal protective equipment (PPE). This shortage has never been greater in the face of the ongoing COVID-19 pandemic and the future upcoming pandemics. Recently, metal-organic Frameworks (MOFs) have been demonstrated their utility for mass manufacturable and effective air filtration devices to filter particulate and viral matters. We synthesized MOFs within seconds and at high yields under the aqueous system. Under this synthesis method, the sequential dip coating (SQD) process is applied to grow MOFs on the commonly available fabrics. During the rapid formation, the MOFs form on the fabrics as well as within the fabrics so that MOFs cannot be detached from the fabrics when the fabrics are washed. Especially, the zirconium-based MOF, UiO-66, production on commonly available fabrics provides an economically capable and simple approach to the large-scale production of MOF-fabric-based filters. Compared to the control fabrics-based filters, UiO-66-fabric based filters show at least 20% higher filter performance as the porous nature of MOFs enhances the sensitivity and selectivity of the particulate and viral matters. The rapid and continuous mass production of MOF-fabric-based filters allows for solving the shortage of PPE in the near future, and the development of effective fabric-based filters.
