Abstract

The present disclosure is directed to steam generation through the efficient harvesting of solar energy. In particular, the present disclosure is directed to bilayered structures that are cost-effective, scalable and/or biodegradable that provide high steam-generation efficiency.

Claims (11)

1. A composition comprising a bilayered structure, wherein the bilayered structure comprises bacterial nanocellulose and at least one nanomaterial in different layers.

2. The composition according to claim 1 , wherein the nanomaterial is selected from the group consisting of graphene oxide, reduced graphene oxide, molybdenum disulfide, polydopamine, functionalized multiwalled carbon nanotubes and combinations thereof.

3. The composition according to claim 2 , wherein the nanomaterial is selected from the group consisting of graphene oxide, reduced graphene oxide, polydopamine, and combinations thereof.

4. The composition according to claim 1 , wherein the composition is biodegradable.

5. The composition according to claim 1 , wherein the nanomaterial is polydopamine.

6. The composition according to claim 1 , wherein the nanomaterial is selected from the group consisting of graphene oxide, reduced graphene oxide and a combination thereof.

7. A composition comprising a bilayered structure, wherein the bilayered structure comprises cellulose and at least one nanomaterial in different layers, wherein the at least one nanomaterial is selected from the group consisting of graphene oxide, reduced graphene oxide and a combination thereof.

8. The composition according to claim 7 , wherein the cellulose is nanocellulose.

9. The composition according to claim 8 , wherein the nanocellulose is selected from the group consisting of cellulose nanofibers, microfibrillated cellulose, nanocrystalline cellulose, bacterial nanocellulose and combinations thereof.
