Abstract
Effect of incorporation of silver metal nano particles (MNP) into the methylacrylamide-2-acrylamido-2-methyl-propanesulphonic acid (MA-AMPS)[MA] copolymer matrix has been investigated by spectroscopic (UV–Vis, FTIR), thermal (DSC) and microscopic (SEM) techniques. The existence of reduced silver MNPs in the copolymer matrix is confirmed by the shift of UV absorption band, suggesting the complexation occurred between silver ion and reactive groups of copolymer. The results are further confirmed by monitoring the shift of FTIR absorption bands. DSC thermograms of the copolymer and nano composite indicate enhancement in thermal stability of copolymer due to the incorporation of silver nanoparticles. SEM micrograph reveals interaction between the silver particles and copolymer matrix.
