Short Communication FTIR Studies on Silver-Poly(Methylmethacrylate) Nanocomposites via In-Situ Polymerization Technique

Silver-poly(methylmethacrylate) (Ag/PMMA) nanocomposites were prepared via in-situ polymerization technique using N,N’-dimethylformamide (DMF) as a medium. The Ag/PMMA was characterized by transmission electron microscopy (TEM) and Fourier transform infrared spectroscopy (FTIR). TEM images of the nanocomposites at 10 % loading of Ag for 80°C revealed the presence of Ag/PMMA particles with an average diameter of 24 nm. When the concentration of Ag/PMMA solution increased, the ester carbonyl group stretching vibration, C=O peaks shifted to lower wavenumbers. At a higher temperature of 120 °C, the intensity of the solutions was 44 % due to the increase of supplied heat to the sample
