INFLUENCE OF THE NATURE OF THE POLYMER STABILIZER ON THE DIMENSIONAL CHARACTERISTICS OF GOLD NANOPARTICLES
The influence of the nature of a polymer stabilizer on the dimensional characteristics of the gold nanoparticles formed in situ by reduction of HAuCl 4 under UV irradiation is demonstrated. Chloroauric acid is present in chitosan solutions and solid organic-inorganic copolymer films based on titanium oxide and ethylene glycol monomethylacrylate. The size distribution of gold nanoparticles ranges from 2 to 7 nm in the chitosan solution, while in a matrix of organic-inorganic copolymers it ranges from 25 to 100 nm.
