A Study on the Synthesis and Characterization of Silver Metal Nano Particles with Acrylic Acid– Acrylamide (Aa) Copolymer as Mediating Agent

Abstract

Silver metal nano-particles (MNP) have been synthesized by chemical methods with acrylic acid- acryl amide (AA) copolymer as mediating agent. Formation and interaction of silver metal nano- particles with AA copolymer has been confirmed by ultraviolet–visible (UV-VIS), Fourier Transform Infrared (FTIR) techniques. Thermal and morphological properties of the composite have been studied by Differential Scanning Calorimetry (DSC) and Scanning Electron Microscope (SEM) techniques. Change in intensity together with shift of FTIR absorption bands in the regions of 3500–3150 cm^-1 and 1700 cm^-1 position in an evidence for interaction of silver metal particles with amide (CONH₂) and carboxylic acid functional (COOH) groups of the copolymer. Presence of 280 nm, 350 nm and 450 nm optical absorption bands indicate the formation and existence of silver nano metal particles in copolymer matrix. DSC thermogram indicates that the thermal stability of the complex is more than the copolymer. The silver nano metal particles are found to lie on the surface of copolymer matrix.
