Air purification system and method for cleaning air
Air purification systems comprising a plurality of disks, and methods for their use, are provided. Each of the plurality of disks comprises a metal substrate, an undercoat layer disposed on the metal substrate, a photosensitive layer disposed on the undercoat layer, and a charge transfer layer disposed on the photosensitive layer.
1. A method for cleaning air comprising:
rotating a plurality of disks, each of the plurality of disks comprising a metal substrate, an undercoat layer disposed on the metal substrate, a photosensitive layer disposed on the undercoat layer, and a charge transfer layer disposed on the photosensitive layer;
irradiating the photosensitive layer with a light to induce an electric charge; and
contacting air and the plurality of disks.
2. The method of claim 1 , wherein the plurality of disks are arranged so that the charge transfer layers of adjacent disks are opposed to each other.
3. The method of claim 1 , wherein the plurality of disks are arranged to that the metal substrates of adjacent disks are opposed to each other.
4. The method of claim 1 , wherein the plurality of disks are arranged as an array.
5. The method of claim 1 , wherein the plurality of disks are mounted by a rotating shaft.
6. The method of claim 5 , wherein the plurality of disks are rotated by a motor connected to the rotating shaft.
7. The method of claim 1 , wherein a protrusion is provided on the metal substrate.
8. The method of claim 1 , further comprising wiping a surface of the metal substrate.
9. The method of claim 1 , further comprising wiping a surface of the charge transfer layer.
10. The method of claim 1 , wherein the metal substrate comprises aluminum, stainless steel, copper, iron, gold or platinum.
11. The method of claim 1 , wherein rotating the plurality of disks comprises rotating the plurality of disks at a rate of about 30 revolutions per minute (rpm) to about 300 rpm.
12. A method for cleaning air comprising:
rotating a plurality of first disks and a plurality of second disks, wherein each of the first disks and the second disks comprises a metal substrate, an undercoat layer disposed on the metal substrate, a photosensitive layer disposed on the undercoat layer, and a charge transfer layer disposed on the photosensitive layer, wherein the plurality of first disks are mounted by a first rotating shaft, wherein the plurality of second disks are mounted by a second rotating shaft, wherein each second disk is positioned in a gap between adjacent first disks;
irradiating each photosensitive layer with a light to induce an electric charge; and
contacting air and the plurality of disks.
13. The method of claim 12 , wherein, for each first disk, the metal substrate of the first disk is opposed to a charge transfer layer of a second disk.
14. The method of claim 12 , wherein, for each first disk, the charge transfer layer of the first disk is opposed to a charge transfer layer of a second disk.
15. The method of claim 12 , wherein, for each first disk, the metal substrate of the first disk is opposed to a metal substrate of a second disk.
16. The method of claim 12 , wherein the plurality of first disks are rotated by a first motor connected to the first rotating shaft and the plurality of second disks are rotated by a second motor connected to the second rotating shaft.
17. The method of claim 12 , wherein the plurality of first disks and the plurality of second disks are rotated by a motor connected to each of the first rotating shaft and the second rotating shaft.
18. The method of claim 12 , wherein a protrusion is provided on the metal substrate of at least one first disk, at least one second disk or a combination thereof.
19. The method of claim 12 , further comprising wiping a surface of the metal substrate of at least one first disk, at least one second disk or a combination thereof.
20. The method of claim 12 , further comprising wiping a surface of the charge transfer layer of at least one first disk, at least one second disk or a combination thereof.
21. The method of claim 12 , wherein each metal substrate comprises aluminum, stainless steel, copper, iron, gold or platinum.
22. The method of claim 12 , wherein rotating the plurality of first disks and the plurality of second disks comprises rotating the plurality of first disks and the plurality of second disks at a rate of about 30 revolutions per minute (rpm) to about 300 rpm.
