A method for manufacturing nano-silver colloids is provided to improve heat transfer efficiency or electric conductivity, by uniformly dispersing nano-silver colloids in a heat transfer medium or electron ink. Ammonia water is added into silver nitrate aqueous solution. Surfactant is added into the solution where the ammonia water is added. Polyhydric alcohol is added into the solution where the surfactant is added, thereby forming silver particles. The polyhydric alcohol is selected from a group consisting of glucose, ethylene glycol, glycerol, threitol, aribitol, mannitol, galacitol, sorbitol, and a mixture thereof. |
