High-efficiency aerosol filters based on silicon
2015-9-25 · The applicability of coated foams as high-efficiency aerosol filters was investigated. • SiC foams were coated with nanowires through a catalyst-assisted pyrolysis process. • Samples were 2–5 orders of magnitude more permeable than commercial HEPA filter. • Increase of filter thickness caused exponential improvement in the collection efficiency.
