Abstract
Radiolytic preparations of silver-polycarbonate (Ag-PC) composites have been characterized for their
structural and antibacterial properties. Rutherford backscattering, X-ray diffractogram, and transmission
electron microscopy measurements verified the presence of face-centered cubic structured Ag nanoparticles.
The microstructural changes of pristine PC and Ag doped PC were monitored using positron annihilation
lifetime spectroscopy (PALS). Experiments indicated a decrease in free volume hole size and fractional
free volume of Ag-PC composites. PALS results were consistent with Doppler broadening spectroscopy
measurements. The antibacterial activity of the Ag-PC composites was evaluated by agar diffusion method
against Gram-negative bacteria and Gram-positive bacteria and showed the prepared composite’s ability to
inhibit bacterial growth.
