Abstract

Printable elastomer materials that are conductive or insulating and that may be printed in three dimensions (3D) for use in applications, including for example fabrication of actuators such as dielectric elastomer actuators (DEAs).

First claim

The invention claimed is:

1. A printable conductive elastomer material, comprising:
a polyol component;
a polymer component;
a chemical component;
an ionic compound component;
a crosslinking agent component; and
a photo initiator component,

wherein the printable conductive elastomer material is conductive.

2. The printable conductive elastomer material according to claim 1 , wherein the polyol component is glycerol.

3. The printable conductive elastomer material according to claim 1 , wherein the polymer component is polyacrylamide.

4. The printable conductive elastomer material according to claim 1 , wherein the chemical component is acrylamide.

5. The printable conductive elastomer material according to claim 1 , wherein the ionic compound component is sodium chloride.

6. The printable conductive elastomer material according to claim 1 , wherein the crosslinking agent component is N,N′-Methylenebisacrylamide.

7. The printable conductive elastomer material according to claim 1 , wherein the photo initiator component is 2-hydroxy-2-methyl-1-phenyl-propan-1-one.

8. A method for creating a conductive elastomer material, comprising the steps of:
dissolving a polyol component and a polymer component in water to obtain a first solution;
adding to the first solution a chemical component and an ionic compound component to obtain a second solution;
mixing with the second solution a crosslinking agent component to obtain a mixture; and
blending into the mixture a photo initiator component to obtain the conductive elastomer material.

9. The method for creating a conductive elastomer material according to claim 8 , further comprising the steps of:
printing the conductive elastomer material using a three-dimensional printer; and
curing the conductive elastomer material using an ultraviolet light source to obtain an object.

10. The method for creating a conductive elastomer material according to claim 8 , wherein the polyol component is glycerol.

11. The method for creating a conductive elastomer material according to claim 8 , wherein the polymer component is polyacrylamide.

12. The method for creating a conductive elastomer material according to claim 8 , wherein the chemical component is acrylamide.

13. The method for creating a conductive elastomer material according to claim 8 , wherein the ionic compound component is sodium chloride.

14. The method for creating a conductive elastomer material according to claim 8 , wherein the crosslinking agent component is N,N′-Methylenebisacrylamide.

15. The method for creating a conductive elastomer material according to claim 8 , wherein the photo initiator component is 2-hydroxy-2-methyl-1-phenyl-propan-1-one.
