From: Sustainable biomass-based filter for high-efficiency PM0.3 filtration
SEM images of (a) zein fibers and (b) zein/CNFs fibers under RH 90%. c Fiber diameter distribution of the D-net fibers. d CLSM images of a D-net fiber with fluorescently labeled zein (FITC-zein) and fluorescently labeled CNFs (CW-CNFs). e Viscosity of zein solution and zein/CNFs changes with evaporation time. f FTIR spectra of CNFs, D-net fibers, zein fibers, and pristine zein. g Porosity and h pore size distribution of corn-based filter with ribbon, rod, and D-net structures. i SEM images of fiber cross section of ribbon structure (RH 30%) and rod structure (RH 90%). Values are shown as mean ± SD, n = 5. Source data are provided as a Source Data file.
