CA 2717665

The invention relates to a pro-cess for the preparation of silver nano parti-cles comprising dissolving a surfactant in ethanol to obtain a first solution; dissolving a silver precursor in water to obtain a second solution; adding the second solution to the first solution to obtain a third solution; dis-solving a reducing agent in water to obtain a reducing agent solution and adding the reduc-ing agent solution to the third solution to ob-tain silver nano particles.

L'invention porte sur un procédé de fabrication de nanoparticules d'argent. Le procédé consiste à dissoudre un tensioactif dans de l'éthanol pour obtenir une première solution ; à dissoudre un précurseur d'argent dans de l'eau pour obtenir une seconde solution ; à ajouter la seconde solution à la première solution pour obtenir une troisième solution ; à dissoudre un agent réducteur dans de l'eau pour obtenir une solution d'agent réducteur ; et à ajouter la solution d'agent réducteur à la troisième solution pour obtenir des nanoparticules d'argent.
