Fabrication of Perfect Branched PVDF/TiO2 Nanofibers for Keeping Food Fresh via One-Step Electrospinning

Nowadays, the attention of researchers about titanium dioxide (TiO2) nanomaterials has increased due to their bactericidal, nontoxic, safe, cost-effective, stable, noncarcinogenic and industrial applications. This study aims to fabricate the electrospun branched PVDF/TiO2 nanofiber webs with tiny diameters and evaluate their performance in food fresh-keeping. The surface morphology, infrared spectroscopy, antibacterial properties and air permeability of the electrospun nanofiber web have been tested. Our results showed that the branched PVDF/TiO2 nanofibers with a diameter of less than 4nm can be electrospun smoothly. Furthermore, these webs have exhibited great potential in preserving the core of bananas fresh owing to their antibacterial properties, nonpoisonous, edible, edible and breathability.
