New emulsion electrospun biodegradable fibers and films PLA/PVP, containing green synthesized hydrozincite – Antibacterial and photocatalytic activity

[Display omitted] •Novel electrospun PLA/PVP/ green synthesized Hydrozincite fibers and films.•The photocatalytic and antibacterial activity of the fibers and film were studied.•Better antibacterial and photocatalytic ability of film towards E. coli and MG. New Poly(lactic acid)/Polyvinylpyrrolidone, containing green synthesized Hydrozincite (GHZ) emulsion electrospun fibers and drop spread films possessing antibacterial and photocatalytic activity were prepared. The PLA/PVP/GHZ films possess higher photocatalytic efficiency towards Malachite Green (MG) dye discoloration (85%) than that of the fibers (62%). The films demonstrate better antibacterial activity to E. coli K-12 with about 6.58 Log CFU/ml in comparison with fibers which expressed about 2.20 Log CFU/ml reduction for 120 h contact.
