Abstract
A nano-silver dispersion and a preparation method thereof is disclosed. The method, includes: mixing γ-aminopropyltriethoxysilane, polyvinylpyrrolidone, sodium lauryl sulfate, silver nitrate and water, and conducting a chelation, to obtain a chelating dispersion, wherein before the mixing, the γ-aminopropyltriethoxysilane is exposed to the air for less than 5 min; and dropwise adding a sodium borohydride solution into the chelating dispersion, to obtain a mixture, and subjecting the mixture to an oxidation-reduction reaction, to obtain the nano-silver dispersion.
