报告摘要:While almost any kind of face mask offers some protection against particles and pathogens of different sizes, the most efficient ones make use of a layered structure where one or more layers are electrically charged.  This electret layer is essential to efficient filtration of difficult-to-capture small particles, yet the exact nature of electrostatic capture with respect to both the charge on the particles and the electret fibres as well as their immediate environment remains unclear.  I will discuss the electrostatic interaction between the surface of a single charged electret fibre and a model of SARS-CoV-2 virus.
