Abstract
A conformable air purification system and methods generally includes optically coupling an active coating comprising a photocatalyst material with a flexible organic light emitting device (OLED) and configuring the flexible media into a desired shape that defines the fluid passageways of then system. The organic light emitting device can be selected to emit light in the visible range when low band gap photocatalyst materials are employed.
Claims19
A fluid purification device for purifying a fluid, the device comprising:
- a flexible lighting substrate adapted to emit visible light, and an optically coupled photocatalyst layer.
A fluid purification system for purifying a fluid, comprising:
- one or more fluid passageways, each one of the one or more fluid passageways comprising a flexible substrate, a flexible organic light emitting device disposed on the flexible substrate, and a flexible photocatalyst layer optically coupled to the organic light emitting device, wherein the photocatalyst layer is configured to contact a fluid flowing through the fluid passageway;
- and
- a power source in electrical communication with the electrodes of the organic light emitting device.
The fluid purification system of claim 13, wherein the cross sectional shapes are different for each one of the one or more fluid passageways.
A fluid purification system comprising:
- a first component comprising a substrate having a OLED structure disposed thereon:
- a second component spaced apart from the first component, the second component comprising a photocatalyst layer disposed on a surface of a substrate and a flexible OLED structure disposed on an opposite surface of the substrate, wherein the photocatalyst layer is facing and in optical communication with the OLED structure of the first component;
- and
- a third component spaced apart from the second component, the third component comprising a flexible substrate having a photocatalyst layer disposed thereon, wherein the photocatalyst layer is facing and in optical communication with the OLED structure of the second component.
A method for purifying a fluid, comprising:
- flowing a fluid into a fluid passageway, the fluid passageway comprising a flexible substrate, a flexible organic light emitting device disposed on the flexible substrate, and a flexible photocatalyst layer optically coupled to the organic light emitting device, wherein the photocatalyst layer is configured to contact the fluid flowing through the fluid passageway and a power source in electrical communication with the electrodes of the organic light emitting device;
- and
- simultaneously emitting light from the organic light emitting device during the flowing of fluid into the fluid passageway.
