Considering the beneficial effects of the use of masks against the spread of influenza viruses and the presence of COVID-19 variants, the habit of wearing a mask become a preferred tool for protection and the fight against viral transmission. Moreover, the improvement of building ventilation is an important mitigation strategy to reduce the spread of disease and lower the risk of exposure. Given that these masks and filters are composed of plastic-based materials having a long afterlife after being discarded, these materials accumulate in landfills and oceans. The goal of this project is to produce multifunctional biodegradable PHBV-based three-layered fibrous mats with antiviral and antibacterial properties for use in face masks and air filters. These biodegradable and functional products will protect the health of Canadians by reducing the spread of viruses, whether via wearing a mask or using an effective filtration device. When installed on a larger scale, these filters will enable schools, workplaces, and offices to benefit from a healthier air environment, reduced virus transmission, and lower economic losses related to absenteeism, all while using more environmentally friendly filters.
