This study aimed to produce polyvinylpyrrolidone/gelatin
(PVP/GEL) nanofibers based on clove essential oil (CLEO) and eucalyptus
essential oil (EEO) through emulsion electrospinning. Firstly, solution
properties such as GC-MS profile, viscosity, conductivity, and surface tension
were investigated. Then, nanofibers were produced under optimum process
parameters and characterized using SEM, FT-IR, and UV-vis. Lastly,
antibacterial activity was determined via the disc diffusion method against Staphylococcus
aureus (S. aureus), Escherichia coli (E. coli), Candida
albicans (C. albicans), Pseudomonas aeruginosa (P.
aeruginosa), and Enterococcus faecalis (E. faecalis). The
major components of CLEO and EEO were determined to be eugenol and 1,8-cineole,
respectively. Conductivity and surface tension decreased and viscosity
increased with increasing concentration of either essential oil. Generally,
addition of CLEO to the polymer solution yielded quite fine nanofibers and
eliminated beads. Moreover, CLEO nanofibers displayed larger inhibition zones
than did EEO nanofibers.
