Abstract

A method including combining an aniline monomer, an oxidant, water and an organic solvent; subjecting the combination to acoustic mixing to form an emulsion; and recovering a polyaniliine from the combination. A method including combining a aniline monomer, an oxidant, water and an organic solvent; forming a polyaniline by acoustic mixing the combination; and recovering the polyaniliine from the combination. A method including forming a combination of an aniline monomer, an oxidant, water and an organic solvent in the absence of an emulsifier; acoustic mixing the combination for a time period to form a polyaniline; and recovering a polyaniliine from the combination.

First claim

What is claimed is:

1. A method comprising:
forming a combination of an aniline monomer, an oxidant, water and an organic solvent at a frequency of 15 Hertz to 2000 Hertz;
subjecting the combination to acoustic mixing at a frequency of 15 Hertz to 2000 Hertz to form an emulsion; and
recovering a polyaniline from the combination.

2. The method of claim 1 , wherein the combination further comprises a dopant.

3. The method of claim 2 , wherein the dopant comprises an acid.

4. The method of claim 1 , wherein subjecting the combination to acoustic mixing comprises acoustic mixing at a frequency of 30 Hertz to 1000 Hertz.

5. The method of claim 1 , wherein subjecting the combination to acoustic mixing comprises subjecting for a period of at least one hour at room temperature.

6. A method comprising:
forming a combination of an aniline monomer, an oxidant, water and an organic solvent at a frequency of 15 Hertz to 2000 Hertz;
forming a polyaniline by acoustic mixing the combination at a frequency of 15 Hertz to 2000 Hertz; and
recovering the polyaniline from the combination.

7. The method of claim 6 , wherein the combination further comprises a dopant.

8. The method of claim 7 , wherein the dopant comprises an acid.

9. The method of claim 6 , wherein the acoustic mixing comprises acoustic mixing at a frequency of 30 Hertz to 1000 Hertz.

10. The method of claim 6 , wherein forming the polyaniline comprises subjecting the combination to acoustic mixing for a period of at least one hour at room temperature.

11. A method comprising:
forming a combination of an aniline monomer, an oxidant, water and an organic solvent in the absence of an emulsifier;
acoustic mixing the combination at a frequency of 15 Hertz to 2000 Hertz for a time period to form a polyaniline; and
recovering a polyaniline from the combination.

12. The method of claim 11 , wherein the combination further comprises a dopant.

13. The method of claim 12 , wherein the dopant comprises an acid.

14. The method of claim 11 , wherein acoustic mixing comprises acoustic mixing at a frequency of 30 Hertz to 1000 Hertz.

15. The method of claim 1 , wherein the time period comprises at least one hour at room temperature.
