Abstract
The in situ gamma ray-assisted diffusion of gold nanoparticles in a polycarbonate film modified the nano-structural and surface properties to enable control of functional use with decreases in the free volume nano-hole size and in the fractional free volume measured using positron annihilation lifetime spectroscopic techniques. Coincidenace Doppler broadened spectra showed the identifiable spreading of the gold broadened region of the intensity ratio relative to the pristine polycarbonate film. These results were further corroborated by x-ray photoelectron spectroscopy and Transmission electron microscopy which showed the diffused gold nanoparticles had an average size of about 8 nm, and also showed the bonding of gold nanoparticles with the oxygen functional groups of polycarbonate film.
