Abstract

Embodiments of the invention relate to jellyfish polymer comprising jellyfish protein and at least one additive, wherein the jellyfish protein comprises mucin and collagen. Further embodiments relate to hydrogels, antibacterial polymers, composite polymers and methods of making the polymers.

First claim

The invention claimed is:

1. A jellyfish polymer comprising jellyfish protein and at least one additive, wherein the additive is selected from the group consisting of: a metal particle, an antibiotic agent, a coloring, guar, agar, alginic acid or a salt thereof, agarose, cellulose, gelatin, glycerol, PVA (polyvinyl alcohol), PANPS (poly(2-acrylamido-2-methylpropanesulfonic acid)), hyaluronic acid; a nanoparticle, a carbon nanotube, a multiwalled nanotube, fullerene, a nanodot, a dye, a nanorod, a cluster compound, graphene, a metal cluster and a polyoxometalate cluster;
wherein the jellyfish protein comprises mucin and collagen.

2. The jellyfish polymer according to claim 1 wherein mucin and collagen are present in the same proportions as in naturally occurring jellyfish.

3. The jellyfish polymer according to claim 1 wherein the nanoparticle is a metal nanoparticle, semiconductor nanoparticle, metal oxide nanoparticle, ceramic nanoparticle, carbon nanoparticle or carbon nanotube.

4. The jellyfish polymer according to claim 1 wherein the nanoparticle is a silver nanoparticle.

5. The jellyfish according to claim 1 wherein the weight ratio between nanoparticle and jellyfish protein is between about 1:5 to about 5:1.

6. The jellyfish polymer according to claim 1 wherein the nanoparticles have an average diameter of about 20-60 nanometers.

7. The jellyfish polymer according to claim 6 wherein the nanoparticles have an average diameter of about 40 nanometers.

8. The jellyfish polymer according to claim 1 in the form of a hydrogel.

9. The jellyfish polymer according to claim 8 , wherein upon exposure to moisture, is capable of adsorbing at least 100% of its weight in water.

10. The jellyfish polymer according to claim 9 , wherein upon exposure to moisture, is capable of adsorbing at least 200% of its weight in water.

11. The jellyfish polymer according to claim 8 comprising between about 20 and about 60 percent jellyfish protein by weight.

12. The jellyfish polymer according to claim 11 comprising about 40 percent jellyfish protein by weight.

13. The jellyfish polymer according to claim 1 comprising less than 17 parts per million (PPM, by weight) Cd, less than 750 PPM Cu, less than 8.5 PPM Hg and less than 150 PPM Pb.

14. The jellyfish polymer according to claim 1 having a Young's modulus of between about 10 kilopascals and about 5000 megapascals.

15. A sanitary hygiene article comprising the polymer according to claim 1 .

16. The sanitary hygiene article according to claim 15 in the form of a diaper, feminine hygienic product, bandage, medical gloves, or medical wrapping material.

17. The sanitary hygiene article according to claim 15 , wherein the jellyfish protein is in the form of a hydrogel.

18. A sanitary wrapping article comprising the polymer according to claim 1 .

19. The sanitary wrapping article according to claim 18 comprising a food wrapped in it.

20. A polymer according to claim 1 wherein the polymer prevents the growth of bacterial microorganisms.

21. A method of manufacturing a jellyfish-derived polymer comprising isolating jellyfish protein from jellyfish; and crosslinking the jellyfish protein to form a polymer or gelation of the protein to form a hydrogel, wherein the jellyfish protein comprises mucin and collagen.

22. The method of claim 21 wherein said mucin and collagen are not separated from each other before the polymer formation.

23. The method of claim 21 , further comprising adding an additive selected from the group consisting of: a metal particle, an antibiotic agent, a coloring, guar, agar, alginic acid or a salt thereof, agarose, cellulose, gelatin, glycerol, PVA (polyvinyl alcohol), PANPS (poly(2-acrylamido-2-methylpropanesulfonic acid)), hyaluronic acid, a nanoparticle, a carbon nanotube, a multiwalled nanotube, fullerene, a nanodot, a dye, a nanorod, a cluster compound, graphene, a metal cluster and a polyoxometalate cluster.
