  • Patent number: 10619066
    Abstract: A metallic nanoparticle dispersion includes metallic nanoparticles and less than 50 ?mol/g metal of an inorganic acid or a compound capable of generating such an acid during curing of a metallic layer or pattern formed from the dispersion. The presence of such small amounts an inorganic acid increases the conductivity of metallic layers or patterns formed from the metallic nanoparticle dispersions at moderate curing conditions.

  • Patent number: 9624386
    Abstract: A method to prepare a metallic nanoparticle dispersion includes the steps of forming a metallic precursor dispersion or solution by adding a metallic precursor to a dispersion medium including: (a) a solvent according to Formula I, and wherein R1 and R2 represent an optionally substituted alkyl group, R1 and R2 may form a ring, (b) a carboxylic acid according to Formula II, R—COOH?? Formula 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.

  • Publication number: 20160083594
    Abstract: A method of preparing a conductive metallic layer or pattern includes the steps of applying a metallic nanoparticle dispersion on a support to obtain a metallic layer or pattern, and contacting the metallic layer or pattern with a solution containing an acid or an acid precursor capable of releasing the acid during curing of the metallic layer or pattern. It has been observed that by contacting the metallic layer or pattern with a solution containing an acid or an acid precursor capable of releasing the acid, higher conductivities at moderate curing conditions are obtained.
