Abstract

The optical absorption spectra measured of radically new nanocomposite of silver nanoparticles and arabinogalactan-g-oligopyrrole block-copolymer have 3 optical bands at 294, 426 and 585 nm. There have been no absorption maxima shifts but only absorption intensity decrease of the first and the sec- ond optical bands during eight months. Reduction of optical absorption intensity at 294 nm is related to decrease of acyl radical quantity in the nanocomposite. Decrease of 0D and 1D nanosilver plasmon absorption intensity at 426 nm can be explained by increase of the nanoparticle size in consequent to nanoparticle coalescence. Optical absorption of nanocomposite at 585 nm is associated with longitudal component of 1D nanosilver plasmon resonance and presence of plasmons in the oligopyrrole chains.
