Abstract Details

, Master of Sciences, Case Western Reserve University, Macromolecular Science and Engineering.
In this thesis, spin-coated pure PVA films and PVA/PVP blend films were used as solid-state polymer matrix, and embedded silver nanoparticles were synthesized by ultraviolet (UV) irradiation method and heating method via in situ reaction. PVA and PVP serve as polyol reductant and stabilizer, respectively. UV-visible spectroscopy was used to characterize the effect of precursor concentration, polymer blend content, and reaction conditions on the size and distribution of silver nanoparticles (AgNPs). The morphology of AgNPs and polymer network were observed by transmission electron microscopy (TEM). The Ag/PVA and Ag/PVA/PVP nanocomposite films were successfully prepared by UV light and thermal-induced reduction of the metal precursor, silver nitrate (AgNO3), and growth of the AgNPs directly in the solid-state polymer film. AgNPs with different sizes ranging from 3 to 15 nm and narrow distribution were synthesized by changing the reaction conditions. Therefore, these synthesis methods are simple in operation and fast in reaction.
