The structural properties of polycarbonate/silicon carbide–tantalum carbide nanocomposites are investigated for antibacterial application. The nanocomposites are prepared by casting method with various ratios of SiC/TaC nanoparticles: 1.2, 2.4, 3.6 and 4.8 wt.%. The experimental re-sults show that high distribution of SiC–TaC nanoparticles inside the pol-ycarbonate matrix. The antibacterial activity of the nanocomposites increases with the increase in the SiC–TaC-nanoparticles’ concentration. Finally, the prepared nanocomposites have high antibacterial activity with a low cost, flexibility and lightweight.
