Abstract

EB irradiation method was used to prepare polyvinyl alcohol (PVA) capped silver nanoparticles under various conditions including PVA concentration, $AgNO_3$ concentration, IPA concentration, and EB dosage. The increase in the distribution of particles size was observed with an increase in the concentrations of PVA, $AgNO_3$, IPA, and EB dosage. $AgNO_3$ concentration, IPA concentration, and EB dosage were found to have a great effect on the amount of silver particles formed in PVA matrix by EB irradiation method. These results were confirmed by XRD, UV, and TEM. XRD (X-ray diffraction) technique confirmed the zero valent state of silver. Optical studies were done using UV-visible spectrophotometer to see the variation of silver particles formed in PVA matrix. Transmission Electron Microscopic (TEM) was employed to show the particle size and distribution of silver foamed in PVA matrix.
