Optical absorption of composite systems with silver nanoparticles dispersed in arabinogalactan and arabinogalactan-g-polypyrrole block copolymer matrices

详细

The absorption of a nanocomposite of silver nanoparticles and arabinogalactan in the UV–Vis spectral range is due to the presence of end aldehyde groups in the arabinogalactan and plasmon vibrations in 0D nanosilver. The absorption spectrum of a fundamentally new nanocomposite of silver with arabinogalactan-g-polypyrrole block copolymer reveals additional long-wavelength overlapping absorption bands resulting from the longitudinal component of plasmon resonance in 1D nanosilver and polarons in polypyrrole.
