System, method, and apparatus relating to colloidosomes

1. A method of making a film or a solid material, comprising the steps of:

providing a vessel having a vessel lower portion oriented and aligned with gravity,

providing a surface in said vessel lower portion,

introducing two immiscible fluids into said vessel,

nanocrystals contained in at least one of said two immiscible fluids,

applying a shear force to said two immiscible fluids and said nanocrystals in a manner that causes said nanocrystals to self-assemble and form colloidosomes, and

evaporating or removing said two immiscible fluids enabling said colloidosomes to amass on said surface in said vessel lower portion to produce dried colloidosomes and make the film or the solid material.

2. The method of making a film or a solid material of claim 1 wherein said vessel lower portion is oriented with gravity aligned to said lower portion allowing said colloidosomes to amass in said lower portion of said vessel on said surface in said vessel lower portion.

3. The method of making a film or a solid material of claim 1 wherein said step of providing a surface in said vessel lower portion comprises providing a substrate with said surface in said vessel lower portion.

4. The method of making a film or a solid material of claim 1 wherein said step of removing said two immiscible fluids to produce dried colloidosomes comprises allowing evaporation of said two immiscible fluids to produce dried colloidosomes.

5. The method of making a film or a solid material of claim 1 wherein said two immiscible fluids are oil and water.

6. The method of making a film or a solid material of claim 1 wherein said two immiscible fluids are hexane and methanol.

7. The method of making a film or a solid material of claim 1 wherein said nanocrystals are metal nanocrystals.

8. The method of making a film or a solid material of claim 1 wherein said nanocrystals are oxide nanocrystals.

9. The method of making a film or a solid material of claim 1 wherein said nanocrystals are organic nanocrystals.

10. The method of making a film or a solid material of claim 1 wherein said nanocrystals are nanocrystals composed of oxides, metals, semiconductors, and organics, and combinations of oxides, metals, semiconductors, and organics.

11. The method of making a film or a solid material of claim 1 wherein said step of evaporating or removing said two immiscible fluids enabling said colloidosomes to amass comprises enabling said colloidosomes to amass and form a single layer of colloidosomes.

12. The method of making a film or a solid material of claim 1 wherein said step of evaporating or removing said two immiscible fluids enabling said colloidosomes to amass comprises enabling said colloidosomes to amass and form multiple layers of colloidosomes.

13. The method of making a film or a solid material of claim 1 wherein said nanocrystals contained in at least one of said two immiscible fluids are obtained by adding nanocrystals of a first material to at least one of said two immiscible fluids and adding nanocrystals of a second material to at least one of said two immiscible fluids wherein said first material and said second material are different materials and wherein said dried colloidosomes include both nanocrystals of a first material and nanocrystals of a second material.

14. A method of making a film or a solid material, comprising the steps of:

providing a vessel;

providing a stabilized emulsion, wherein said step of providing a stabilized emulsion includes providing two immiscible fluids with nanocrystals in at least one of said two immiscible fluids, applying a shear force to said two immiscible fluids and said nanocrystals in a manner that causes said nanocrystals to self-assemble and form colloidosomes;

providing said stabilized emulsion in said vessel;

providing a first electrode in said vessel;

providing a second electrode in said vessel;

providing a power source connected to said first electrode and connected to said second electrode;

energizing said first electrode and said second electrode using said power source to charge said colloidosomes causing said colloidosomes to migrate to said first electrode and produce a colloidosomes accumulate on said first electrode;

enabling said colloidosomes to amass and form a colloidosomes structure on said first electrode, and

removing said colloidosomes structure from said first electrode to produce dried colloidosomes and make the film or the solid material.

15. The method of making a film or a solid material of claim 14 wherein said step of enabling said colloidosomes to amass and form a colloidosomes structure on said first electrode comprises enabling said colloidosomes to amass and form a single layer of colloidosomes on said first electrode.

16. The method of making a film or a solid material of claim 14 wherein said step of enabling said colloidosomes to amass and form a colloidosomes structure on said first electrode comprises enabling said colloidosomes to amass and form multiple layers of colloidosomes on said first electrode.

17. The method of making a film or a solid material of claim 14 wherein said step of providing two immiscible fluids with nanocrystals in at least one of said two immiscible fluids comprises providing two immiscible fluids with nanocrystals of a first material in at least one of said two immiscible fluids and providing two immiscible fluids with nanocrystals of a second material in at least one of said two immiscible fluids wherein said first material and said second material are different materials.
