System and method for engineered ceramic packages for use in fluid treatment technologies

1. A method for making a ceramic mini-tube configured for use in a fluid modification system, the method comprising:

using an electrospinning system to receive a quantity of precursor solution;

using the electrospinning system to create an electric field which causes the precursor solution, when emitted, to be stretched into a fiber jet;

depositing the fiber jet on a moving collector resulting in a fiber mat made up of pre-ceramic nanofibers;

removing the fiber mat from the collector, wherein the fiber mat is formed into a non-flat shape;

further processing the fiber mat so that the fiber mat retains the non-flat shape; and

performing a heat treatment operation to convert the fiber mat into a ceramic structure having the non-flat shape.

2. The method of claim 1 , wherein the processing of the fiber mat includes at least one of:

utilizing heating of the fiber mat to cause the fiber mat to retain the non-flat shape; or

applying adhesive bonding to the fiber mat to cause the fiber mat to retain the non-flat shape.

3. The method of claim 2 , wherein depositing the fiber jet on a collector produces fibers including:

an average diameter between at least 50 nm to 100 nm; and

a fiber mat thickness between 10 nm-400 μm or a fiber mat area density of between 1-100 g/m 2 .

4. The method of claim 1 , wherein the moving collector comprises at least one of the following components, with or without a cover film or coating:

a rotating mandrel; or

a rotating drum.

5. The method of claim 4 , wherein the moving collector comprises the rotating mandrel, and wherein the method further comprises removing the fiber mat from the rotating mandrel after ceasing rotation of the rotating mandrel, such that the rotating mandrel forms a stationary mandrel, and by rolling the fiber mat off of an end of the stationary mandrel, wherein the fiber mat forms a toroidal shaped structure once removed from the stationary mandrel.

6. The method of claim 4 , wherein the collector comprises the rotating drum, and wherein removal of the fiber mat from the rotating drum occurs after ceasing the rotation of the drum and produces at least one of a sheet of the nanofiber mat or a roll of the nanofiber mat, that can be subsequently cut to size, formed by rolling over a mandrel, and treated with heat to retain the non-flat shape.

7. The method of claim 1 , wherein the heat treatment operation converts pre-ceramic nanofibers with an average diameter of 100 nm or larger into ceramic nanofibers with an average diameter of 50 nm or larger.

8. The method of claim 1 , wherein removing the fiber mat from the collector, to form the fiber mat into a shape, comprises forming the fiber mat into a toroidal shape.

9. The method of claim 8 , wherein after performing the heat treatment operation, the ceramic structure is a mini-tube.

10. The method of claim 9 , wherein the ceramic mini-tube has a diameter of about 1 mm-2 mm.

11. The method of claim 9 , wherein the ceramic mini-tube has a length of at least 1.0 mm.

12. The method of claim 9 , wherein the ceramic mini-tube has pores about 1 μm in size.

13. A method for making a ceramic mini-tube configured for use in a fluid modification system, the method comprising:

using an electrospinning system to receive a quantity of precursor solution;

using the electrospinning system to create an electric field which causes the precursor solution, when emitted, to be stretched into a fiber jet;

depositing the fiber jet on a rotating collector resulting in a fiber mat;

removing the fiber mat from the collector, wherein the fiber mat is formed into a toroidal shape;

further processing the fiber mat so that the fiber mat retains the toroidal shape; and

performing a heat treatment operation to convert the fiber mat into a ceramic mini-tube having the toroidal shape; and

wherein the ceramic mini-tube comprises a diameter of at least about 1 mm.

14. The method of claim 13 , wherein the depositing the fiber jet on a rotating collector comprises depositing the fiber jet on at least one of:

a rotating mandrel; or

a rotating drum.

15. The method of claim 13 , wherein the ceramic mini-tube includes at least one of a diameter of 1 mm-2 mm, or a length of at least 1 mm, or pores about 1 μm in size.
