(a) Scanning electron microscopy image of electrospun fibers of PVA and LDH fillers dried at 75°C (PF75). (b) Scanning electron microscopy image of annealed fibers of PVA and LDH fillers (CF250). (c) High-resolution image showing individual ZnO nanoparticle fillers inside the fibers. (d) High-resolution image of the dispersion of nanoparticles inside the PVA matrix. (e) Dispersion of the nanoparticles is centered at 45 nm, and the size distribution fits a Gaussian curve with a full width at half maximum of ~15 nm.
