| Abstract: | The features of nanoparticle formation by the radiation-chemical reduction of Cu2+ ions in polyacrylic acid-polyethyleneimine complexes have been studied. It has been shown that the swollen film/aqueous alcohol
medium interphase exchange of the reducing species and the specifics of X-ray energy transfer play an important role in the
formation of metal particles in the subsurface layer of polymer matrixes. An analysis of EPR and X-ray diffraction data shows
that an acetaldehyde admixture increases the Cu2+ reduction rate of and enables the growth of nanoparticles. |
