Abstract
The invention relates to a method for preparing silver nanoparticles having a diameter lower than 80 nm, and dispersed in a polymer matrix in a concentration higher than 1 M, that comprises the following steps: i) mixing an organic silver salt and a polymer having an alcohol terminal function in a solvent containing at least one alcohol fraction; ii) agitating and heating the mixture obtained during the previous step; and iii) separating the polymer phase charged with silver nanoparticles.

A method for preparing silver nanoparticles with a diameter of less than 100 nm, dispersed in a polymeric matrix at a concentration above 1 M, including the following steps:
- i. reacting an organic salt of silver and a polymeric agent for nucleating and stabilizing silver nanoparticles,
- ii. mixing the reaction medium obtained earlier with a reducing agent having a defined reduction potential and having coordination affinity with Ag+ ions,
- iii. concentrating and separating the polymer matrix containing the silver nanoparticles.
