ANTIBACTERIAL AND DIELECTRIC PROPERTIES OF TEXTILE MATERIALS MODIFIED WITH HERBAL EXTRACT OF Picea omorika AND THE COPPER FERRITE NANOPARTICLES
In this paper, cotton, polyester and cotton/polyester fabrics were modified by using herbal extract of Picea omorika and copper ferrite nanoparticles and their antibacterial and dielectric properties were investigated. Antibacterial activities of all samples were examined against Escherichia coli and Staphylococcus aureus. Most of the fabrics modified by copper ferrite showed antibacterial activities against Escherichia coli, while the addition of the herbal extract improved their antibacterial protection. Dielectric properties were measured in frequency range from 24 Hz to 75 kHz at room temperature and the results showed that the modification of all three fabrics with copper ferrite caused increase in their electrical conductivity. The obtained results point to the possibility of using investigated fabrics for antibacterial protection as well as for the electromagnetic shielding application.
