Abstract

According to certain embodiments, a method of producing a pattern on a substrate comprises securing a flexible polymeric substrate, printing a layer of ink as a negative pattern on the substrate, and placing the flexible polymeric substrate in a vacuum chamber. The method further includes uniformly applying, while the flexible polymeric is under a vacuum in the vacuum chamber, a layer of material over both the layer of ink and the substrate via physical vapor deposition and then removing the flexible polymeric substrate from the vacuum chamber. The method further includes removing the ink and material applied over the ink by immersing the flexible polymeric substrate in a solvent such that it results in a desired pattern of the material on the flexible polymeric substrate.

First claim

The invention claimed is:

1. A method of producing a pattern on a substrate, the method comprising:
securing a flexible polymeric substrate;
printing a layer of ink as a negative pattern on the flexible polymeric substrate;
placing the flexible polymeric substrate in a vacuum chamber;
while the flexible polymeric substrate is under a pressure in the vacuum chamber that is less than an atmospheric pressure, uniformly applying a layer of material over the layer of ink and over the flexible polymeric substrate via physical vapor deposition;
removing the flexible polymeric substrate from the vacuum chamber; and
removing the ink and material applied over the negative pattern of ink by:
immersing the flexible polymeric substrate in a solvent; and
utilizing one of at least ultrasonic agitation and mechanical agitation, wherein removing the ink and material applied over the negative pattern of ink results in a desired pattern of the material on the flexible polymeric substrate.

2. The method of claim 1 , wherein the thickness of the layer of ink is greater than the thickness of the layer of applied material.

3. The method of claim 1 , wherein the flexible polymeric substrate is Kevlar.

4. The method of claim 1 , wherein the applied material comprises one of a metallic material, a dielectric material, and a compounded material.

5. The method of claim 1 , wherein the ink is a water-based ink and the solvent is water.

6. The method of claim 1 , wherein printing the layer of ink comprising printing using an inkjet printing process.

7. The method of claim 1 , further comprising drying the flexible polymeric substrate and the desired pattern of the material after the step of removing the ink and material applied over the negative pattern of ink.

8. A method of producing a pattern on a substrate, the method comprising:
securing a substrate;
printing a layer of ink as a negative pattern on the substrate;
placing the substrate in a vacuum chamber;
while the substrate is under a pressure in the vacuum chamber that is less than an atmospheric pressure, applying a layer of material over the layer of ink and over the substrate via physical vapor deposition;
removing the substrate from the vacuum chamber; and
removing the ink and material applied over the negative pattern of ink by:
immersing the substrate in a solvent; and
utilizing one of at least ultrasonic agitation and mechanical agitation, wherein removing the ink and material applied over the negative pattern of ink results in a desired pattern of the material on the substrate.

9. The method of claim 8 , wherein the substrate comprises a flexible polymeric substrate.

10. The method of claim 8 , wherein applying the layer of material comprises uniformly applying the layer of material.

11. The method of claim 8 , wherein the applied material comprises one of a metallic material, a dielectric material, and a compounded material.

12. The method of claim 8 , wherein printing the layer of ink comprising printing using an inkjet printing process.
