Abstract

A single-step synthesis of homogenous Ag/PVA nanocomposites is carried out and characterized by X-ray diffraction. A validation of the crystal information is established by transmission electron microscopy (TEM) and a homogenous mixing morphology is confirmed by SEM micrographs. Surface plasmon resonance (SPR) optical absorption shows a red shift compared to bare Ag NPs. The degradation mechanisms are explained for both pristine PVA and Ag/PVA nanocomposites, aided by the increase in thermal stability of the PVA support with an enthalpy change for each decomposition reaction.
