Syntheses of Silver Nanoparticles in the Matrices of Block and Graft Copolymers and Polymer-Inorganic Hybrid in Aqueous Solutions

In the present work we have synthesized two‐component block‐ and graft copolymers MOPEO‐b‐PAAm, PAAm‐b‐PEO‐b‐PAAm and PVA‐g‐PAAm comprised methoxypoly(ethylene oxide), poly(ethylene oxide) or poly(vinyl alcohol) and chemically complementary polyacrylamide and also the grafted polymer‐inorganic hybri...

Description
Summary:In the present work we have synthesized two‐component block‐ and graft copolymers MOPEO‐b‐PAAm, PAAm‐b‐PEO‐b‐PAAm and PVA‐g‐PAAm comprised methoxypoly(ethylene oxide), poly(ethylene oxide) or poly(vinyl alcohol) and chemically complementary polyacrylamide and also the grafted polymer‐inorganic hybrid SiO2‐g‐PAAm based on monodispersed silica nanoparticles. These copolymers we used as special matrices in the process of borohydride reduction of Ag+ ions. It was established the influence of chemical nature, molecular architecture and concentration of the matrices and the content of silver nitrate on some reaction parameters, size and stability of Ag‐nanoparticles in aqueous solutions.
