As contagious bio-aerosols continue to impact our society, we examine how the morphological traits of large-scale (15 cm x 93 cm), uniformly thick, electrospun Nylon membranes can contribute to the development of diagnostic, sensor driven face masks for capturing exhaled breath content. In our study, we compare the capture efficiencies of three types of large-scale Nylon-6 nanofiber membranes against those of commercial control textiles for capturing in-lab simulated salt breath aerosols. One of the electrospun membranes was also surface functionalized via grafting technique. The fabrication, functionalization, and exhaled aerosol capture of these large-scale membranes underscores the importance of assessing the lifetime, and usability, of electrospun materials before future integration with diagnostic sensing platforms can be successfully achieved.

In this study, we combine Nylon 6 nanomembranes with tulle and organza fashion fabrics to construct a full-scale, flying kite. For the first time, this work demonstrates the processing of electrospun nanofabrics using laser cut and ultrasonic technologies. The composite fabrics were analysed for their morphological and mechanical properties. The fracture strain of the nanomembrane–tulle composites increased 58–171% compared to the control samples due to nanofibre entanglements on the open weave structure of tulle. The ultrasonic sewn fabric regions endured 169% greater applied stress with the addition of the organza fabric and the seaming process compared to the nanomembrane–tulle composite. [less ▲]
