摘要: We report a new approach for fabricating layer-by-layer (LBL) structured ultrathin hybrid films on electrospun nanofibres. Oppositely charged anatase TiO2 nanoparticles and poly(acrylic acid) (PAA) were alternately deposited the surface of negatively cellulose acetate (CA) nanofibres using electrostatic LBL self-assembly technique. The fibrous mats characterized by wide-angle x-ray diffraction, Fourier transform infrared spectroscopy, scanning electron microscopy, transmission microscopy Brunauer–Emmett–Teller (BET) area techniques. crystalline phase remained unchanged in resultant TiO2/PAA coated CA mats. Moreover, film fibres showed rough surfaces with grains due to deposition aggregated particles. average diameter increased from 344 584 nm BET 2.5 6.0 m2 g−1 after coating five bilayers films.
