Abstract

Processes for depositing functionalized nanoparticles upon a non-conductive substrate are disclosed herein. The processes may include the step of aerosolizing one or more particles into suspension within a gas, each of the one or more particles comprising functionalized nanoparticles having an electric charge. The processes may include the step the step of attracting the one or more particles onto a non-conductive substrate by a static electric charge opposite of the electric charge, wherein at least portions of the non-conductive substrate are having the static electric charge. The processes may include the step of depositing the functionalized nanoparticles onto the non-conductive substrate.

First claim

What is claimed is:

1. A process, comprising the steps of:
aerosolizing one or more particles into suspension within a gas, each of the one or more particles comprising functionalized nanoparticles having an electric charge;
attracting the one or more particles onto a substrate by a static electric charge opposite of the electric charge, at least portions of the substrate having the static electric charge, the substrate being porous and non-conductive; and
depositing the functionalized nanoparticles onto the substrate.

2. The process of claim 1 , further comprising the step of:
bonding the functionalized nanoparticles with the non conductive substrate.

3. The process of claim 1 , further comprising the step of:
forming the functionalized nanoparticles into a pattern on the substrate.

4. The process of claim 3 , wherein the pattern forms a hierarchical structure.

5. The process of claim 1 , further comprising the step of:
measuring a change in an electrical property of a sensor element comprising the substrate with the functionalized nanoparticles deposited thereupon.

6. The process of claim 1 , wherein the functionalized nanoparticles are electrically conductive.

7. The process of claim 1 , further comprising the step of:
using an inkjet of an inkjet printer in performing the step of aerosolizing one or more particles into suspension within a gas.

8. The process of claim 1 , wherein the functionalized nanoparticles comprise carbon.

9. The process of claim 1 , wherein the functionalized nanoparticles are being deposited onto surfaces of pores within the substrate.

10. A process, comprising the steps of:
forming a nanoparticle printer ink comprising functionalized nanoparticles having an electric charge; and
depositing the functionalized nanoparticles upon a substrate by inkjet printing the nanoparticle printer ink onto the substrate using an inkjet printer, the substrate having an induced electric field attracting the functionalized nanoparticles onto the substrate, and the substrate being porous and non-conductive.

11. The process of claim 10 , further comprising the step of:
arranging the functionalized nanoparticles into a pattern on the substrate.

12. The process of claim 11 , wherein the pattern forms a hierarchical structure.

13. The process of claim 10 , further comprising the step of:
measuring a change in an electrical property of a sensor element comprising the substrate with the functionalized nanoparticles deposited thereupon.

14. The process of claim 10 , wherein the functionalized nanoparticles are electrically conductive.

15. A process, comprising the steps of:
suspending a nanoparticle dispersion within a gas as particles having an electric charge, the particles comprising functionalized nanoparticles;
inducing an electric field about a substrate, the substrate being porous and non-conductive;
attracting the functionalized nanoparticles to the substrate using the electric field; and
depositing the functionalized nanoparticles onto the substrate.

16. The process of claim 15 , further comprising the step of:
bonding the functionalized nanoparticles with the substrate.

17. The process of claim 15 , further comprising the step of:
forming a pattern comprising the functionalized nanoparticles on the substrate.

18. The process of claim 15 , wherein the functionalized nanoparticles are electrically conductive.

19. The process of claim 15 , wherein the functionalized nanoparticles comprise carbon.

20. The process of claim 15 , further comprising the step of:
measuring a change in an electrical property of a sensor element comprising the substrate with the functionalized nanoparticles deposited thereupon.
