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. 2019-05-23 English text Case Western Reserve University School of Graduate Studies / OhioLINK http://rave.ohiolink.edu/etdc/view?acc_num=case1555418297166208 http://rave.ohiolink.edu/etdc/view?acc_num=case1555418297166208 unrestricted This thesis or dissertation is protected by copyright: all rights reserved.
