CHARACTERIZATION OF SILVER NANOPARTICLES DISPERSED IN ORGANIC COMPOUND AND NATURAL POLY

Abstract

The present work investigated about morphology of Silver nanoparticles by using laser ablation which is a green technique. A Q-Switched Nd: YAG pulsed laser with 532 nm wavelength and 360 mJ/pulse energy used for synthesis of silver nanoparticles from silver plate with 99% purity for 30 min in organic compound such as ethylene glycol and natural polymer such as chitosan. The media (Ethylene glycol and chitosan) allowed the formation of nanoparticles with well dispersed. The spherical silver nanoparticles with different sizes obtained in various liquid media that was changed just over from 22 nm to about 10 nm in ethylene glycol and chitosan solution respectively. Additionally, the morphology of nanoparticles was compared with distilled water as a reference. The results showed silver nanoparticles proficiently dispersal in the chitosan solution with a considerable size reduction in comparison with other media.
