Finding F-0137

“By changing the concentration of TPU in the polymer solution, PM2.5 removal efficiency of nanofiber-based air filter can be up to 99.654% with good optical transparency of 60%, and the contact angle and the ventilation rate of the nanofiber-based air filter is 128.5° and 3480 mm/s, respectively.”

Structure

Factor: Particulate matter (PM₂.₅ and PM₁₀)
Intervention: Air filtration and air purifiers
Setting: laboratory, CN
Study design: laboratory materials study: thermoplastic polyurethane nanofibers electrospun onto conductive mesh with a rotating bead spinneret, filtration efficiency tested against PM2.5 (class 4)
Effect: other 99.654
Caveat: a laboratory material result, not a field measurement; printed as up to 99.654 %
