Abstract

A composition for forming a conductive film. The composition comprises a plurality of nanowires comprising silver; a latex comprising polymer particles; and an aqueous-based carrier.

First claim

1 . A composition for forming a conductive film, the composition comprising:
a plurality of nanowires comprising silver; a latex comprising polymer particles having a glass transition temperature of 25° C. or less; and an aqueous-based carrier, wherein a weight ratio of the nanowires to the polymer particles ranges from about 6:1 to about 2:1.

2 . (canceled)

3 . (canceled)

4 . The composition of claim 1 , wherein the polymer particles have an average particle size of 300 nm or less.

5 . The composition of claim 1 , wherein the polymer particles comprise a polymer selected from the group consisting of an acrylate polymer, a polyester, a polyurethane and combinations thereof.

6 . The composition of claim 1 , wherein the polymer particles comprise an acrylate polymer.

7 . The composition of claim 1 , wherein the amount of nanowires in the composition ranges from about 1 mg/mL to about 10 mg/mL.

8 . (canceled)

9 . The composition of claim 1 , wherein an average thickness of the nanowires is about 50 nm or less.

10 . The composition of claim 9 , wherein an average length of the nanowires ranges from about 10 microns to about 100 microns.

11 . A composition for forming a conductive film, the composition comprising:
a plurality of nanowires comprising silver; a latex comprising polymer particles having a glass transition temperature of 25° C. or less; and an aqueous-based carrier, wherein a weight ratio of the nanowires to the polymer particles ranges from about 10:1 to about 2:1.

12 . (canceled)

13 . The composition of claim 11 , wherein the polymer particles have an average particle size of 300 nm or less.

14 . The composition of claim 11 , wherein the polymer particles comprise a polymer selected from the group consisting of an acrylate polymer, a polyester, a polyurethane and combinations thereof.

15 . The composition of claim 11 , wherein the polymer particles comprise an acrylate polymer.

16 . The composition of claim 11 , wherein the amount of nanowires in the composition ranges from about 1 mg/mL to about 10 mg/mL.

17 . The composition of claim 11 , wherein a weight ratio of the nanowires to the polymer particles ranges from about 6:1 to about 2:1.

18 . The composition of claim 11 , wherein an average thickness of the nanowires is about 50 nm or less.

19 . The composition of claim 18 , wherein an average length of the nanowires ranges from about 10 microns to about 100 microns.

20 . The composition of claim 1 , wherein the latex particles are fusable together so as to form a continuous polymer layer in which the nanowires are embedded if the composition is dried at temperatures of 150° C. or less.
