Abstract

A method of increasing conductivity of an ink, comprises orienting particles in the ink. The ink comprises the particles and solvent, and the particles are conductive anisotropic particles.

Claims (7)

1. A method of increasing conductivity of an ink, comprising:

rubbing the ink to increase conductivity of the ink; followed by conducting electricity through the ink,

wherein the ink comprises conductive non-spherical particles comprising carbon, and a solvent,

the ink is on a substrate, and

the method is carried out without curing at a temperature of at least 50° C. between the rubbing and the conducting.

2. The method of claim 1 , wherein the ink further comprises a binder.

3. The method of claim 1 , wherein the particles are selected from the group consisting of graphite, carbon fibers and nanotubes.
