Abstract

A metal nanoparticle composition includes water and a water-soluble polymer having both carboxylic acid and sulfonic acid groups. Silver nanoparticles are dispersed in the water and the weight ratio of the polymer to silver is from 0.008 to 0.1.

Claims (15)

1. An aqueous metal nanoparticle composition comprising:

water;

a water-soluble polymer having both carboxylic acid and sulfonic acid groups, wherein the water-soluble polymer is selected from the group consisting of poly(4-styrenesulfonic acid-co-maleic acid) and poly(4-styrenesulfonic acid-co-acrylic acid); and

silver nanoparticles dispersed in the water, wherein the weight ratio of the polymer to silver is from 0.008 to 0.1.

2. The aqueous metal nanoparticle composition of claim 1 wherein the sulfonic acid group is formed from styrenesulfonic acid, 3-sulfopropyl acrylate, 3-sulfopropyl methacrylate, 2-sulfoethyl methacrylate, 3-sulfobutyl methacrylate, or 2-acrylamido-2-methylpropane sulfonic acid.

3. The aqueous metal nanoparticle composition of claim 1 wherein the carboxylic acid group is formed from acrylic acid, methacrylic acid, ethacrylic acid, itaconic acid, maleic acid, fumaric acid, monoalkyl itaconate, monoalkyl maleate, citraconic acid, styrenecarboxylic acid, 2-carboxyethyl acrylate or 2-carboxyethyl acrylate oligomers.

4. The aqueous metal nanoparticle composition of claim 1 wherein the molar ratio of sulfonic acid groups to carboxylic acid groups is in a range of 0.05 to 5.

5. The aqueous metal nanoparticle composition of claim 1 wherein the weight ratio of the polymer to silver is from 0.008 to 0.04.

6. The aqueous metal nanoparticle composition of claim 1 wherein the weight ratio of the polymer to silver is from 0.008 to 0.02.

7. The aqueous metal nanoparticle composition of claim 1 further including a humectant, a surfactant, a latex polymer, a thickener, a colorant, a cross-linker, or combinations thereof.

8. The aqueous metal nanoparticle composition of claim 1 wherein the weight percentage of silver in the composition is greater than 10%.

9. The aqueous metal nanoparticle composition of claim 1 wherein the weight percentage of silver in the composition is from 60 to 90% and the composition has a viscosity of less than 100 centipoise.

10. The aqueous metal nanoparticle composition of claim 9 wherein the weight percentage of silver in the composition is from 60 to 80% and the composition has a viscosity of less than 50 centipoise.

11. The aqueous metal nanoparticle composition of claim 10 wherein the weight percentage of silver in the composition is from 60 to 75% and the composition has a viscosity of less than 20 centipoise.

12. The aqueous metal nanoparticle composition of claim 1 wherein the metal nanoparticle composition has a surface tension of above 50 dynes/cm.
