Abstract
- Electret fiber filtration materials prepared by electrostatic spinning and corona polarization have drawn significant interest in treating radioactive aerosols. In this study, a three-dimensional biomass-based electret nanofiber aerogel material with high dust capacity, high filtration efficiency and low-pressure drop was created by pore structure regulation. The results showed that aerogels with good charge capture and storage ability were obtained by regulating the concentration of tert-butanol and ethylcellulose fiber suspension, and the pre-freezing temperature. The initial surface potential and stable surface potential increased from 0.85 and 0.05 kV to 1.37 and 0.15 kV respectively. Furthermore, the purification time was reduced from 44 to 15 min.
