Abstract

A method to prepare a metallic nanoparticle dispersion comprising the steps of: - forming a metallic precursor dispersion or solution by adding a metallic precursor to a dispersion medium comprising; (a) a solvent according to Formula I, and wherein R 1 and R 2 represent an optionally substituted alkyl group, R 1 and R 2 may form a ring, (b) a carboxylic acid according to Formula II, €ƒ€ƒ€ƒ€ƒ€ƒ€ƒ€ƒ€ƒ R-COOH€ƒ€ƒ€ƒ€ƒ€ƒFormula II wherein R is an optionally substituted C2-C7 alkyl, alkenyl or alkynyl group, - reducing the metallic precursor with a reducing agent to form metallic nanoparticles, - sedimenting the metallic nanoparticles to obtain a highly concentrated metallic nanoparticle dispersion comprising at least 15 wt % of metallic nanoparticles.
