The present work aims to fabricate the polystyrene (PS)–polycarbonate (PC)/cobalt (II) oxide nanoparticles (Co2O3 NPs)–silicon carbide nanoparticles (SiC NPs) nanocomposites’ films to use in different antibacterial applications. The structural properties and antibacterial activity of (PS– PC/Co2O3–SiC) nanocomposites are studied. The structural properties include data of field emission scanning electron microscopy (FE–SEM) and optical microscopy (OM). The field emission scanning electron microscopy (FE–SEM) and optical microscopy (OM) confirm that the (Co2O3/SiC) NPs are distributed uniformly throughout the PS/PC blend. The results of antibacterial testing show that the diameter of inhibition zone increases with an increase in the (Co2O3/SiC) NPs’ content. The diameters of inhibition zones for the gram-negative bacteria (Salmonella) are bigger than the diameters of the inhibition zones for the gram-positive bacteria (Staphylococcus aureus). The final results indicate that the (PS–PC/Co2O3–SiC) nanocomposites’ films have good antibacterial activity. [ABSTRACT FROM AUTHOR] |
