Production and characterization of medical nanofiber based filters
Original language description
Nanofiber based filters are promising materials for medical applications for filtering bacteria?s or even viruses due to their very small fiber and pore sizes. In this work, a polyurethane nanofiber based filter was produced via electrospinning process and consequently characterized experimentally in the ultrafine particle size range (20- 400 nm). A 3D filtration model utilizing realistic SEM image based 3D structure model, transition/free molecular flow regime, Brownian diffusion, particle-particle interactions, particle-fiber interactions, aerodynamic slip and sieve has been proposed and validated for nanofiber based filters optimization. By using the proposed theoretical approach for the 3D filter clogging modeling, it has been found that the decrease in the fiber-particle friction coefficient leads to higher pressure drop, lower filtration efficiency, lower quality factor and lower quality factor sensitivity.
