A method for preparing a nanosilver suspension is provided to produce a high-concentration suspension that has excellent conductivity and offers good-quality paste inks for forming conductive films. A method for preparing a nanosilver suspension includes the steps of: reacting carboxylic acid, an amine-based solution, and a silver salt to produce a dispersing agent; and preparing a nanosilver suspension having high concentration and high conductivity using the dispersing agent. The silver salt is any one selected from silver nitrate or silver oxide. The carboxylic acid is any one selected from C1-8 carboxylic acids(formic acid, acetic acid, etc), or mixtures thereof. The amine-based solution is any one selected from C1-8 primary or secondary amine-based solutions, or mixtures thereof. |
