Abstract

Potentiostatic formation of the polymer/silver nanoparticles composite. L.G. KOLZUNOVA (Institute of

The fundamental possibility of the formation of a PMAA film / AgNPs composite using the stage of electrochemical
immobilization of silver nanoparticles in the mode of potentiostatic electrolysis into a polymethylolacrylamide matrix
has been shown. It was found that the silver mass depends on the potential and time of electroreduction of silver ions, the
composition of the background electrolyte. The optimal parameters for introducing silver nanoparticles into the polymer
film were determined: E = 170 mV, electrolysis time 10–15 min, background electrolyte 0.1 mol/l KNO₃ + 0.01 mol/l AgNO₃.
It was shown that AgNPs particles had a spherical shape and their average radius was 6–10 nm.
