Polymer-grafted cotton fabrics with high filtration efficiency for reusable personal protective masks
The filtration efficiency of cloth masks for small harmful particles is usually low because of the large pore size of fabrics and the difficulty to choose appropriate fabric specifications. In this study, the polymers with antibiotic groups of quaternary amines were grafted onto cotton fabrics for achieving both satisfactory antibiotic and filtering performance. The results indicated that the pore size of the fabrics grafted with polymer brushes was significantly reduced and thus the filtration efficiency of polymer-grafted cotton fabrics can be increased to 81.5% ± 7.8% from 17.5% ± 2% of original fabrics under the tested level of 0.3 μm particles with 85 L/min flowing rate. The filtration efficiency of treated fabrics was comparable to the medical masks currently used in clinic. Moreover, the grafted fabrics also exhibited excellent antibacterial performance and washability. After 20 cycles of washing, they still had about 75.9% filtration efficiency and 99.9% bacterial inhibition rate for E. coli. This work could inspire the development of reusable and sustainable facemasks with effective personal protection for reducing the spread of COVID-19 and other infectious diseases. Graphical abstract.
