RADIATION-CHEMICAL REDUCTION OF SILVER IONS IN AQUEOUS SUSPENSIONS OF POLYVINYLTRIAZOLE: KINETICS OF NANOPARTICLE FORMATION
The radiation-chemical preparation of silver nanoparticles is a promising approach for the synthesis of antibacterial materials in the matrix of non-toxic poly-1-vinyl-1,2,4-triazole. The use of optical spectroscopy and electron transmission microscopy has shown that nanoparticles with an average size of 4 nm are formed in irradiated suspensions of polyvinyltriazole. Analysis of the data of optical spectroscopy revealed that the formation of nanoparticles occurs in several stages. The formation of clusters dominates at the ﬁ rst stage; the second stage is characterized by the assembly of nanoparticles due to the reduction of silver ions on the surface of the clusters.
