Abstract

A vaporization device includes a cartridge having a reservoir that holds a vaporizable material, a heating element, and a wicking element that can draw the vaporizable material to the heating element to be vaporized. The vaporizer cartridge is configured for coupling to a vaporizer device body and containing a vaporizable material. Various embodiments of the vaporizer cartridge are described that include an organic bifunctional wick-heater assembly using porous organic-based material. Related systems, methods, and articles of manufacture are also described.

Claims (42)

1. A cartridge for a vaporizer device, the cartridge comprising:

a reservoir configured to contain a vaporizable material; and

an atomizer configured to vaporize the vaporizable material, the atomizer comprising a porous organic substrate configured to draw the vaporizable material from the reservoir, the porous organic substrate further configured to receive an electrical current to vaporize the vaporizable material,

wherein the porous organic substrate comprises a graphene and polymer aerogel.

2. The cartridge of claim 1 , further comprising:

a condensation chamber in fluid communication with the atomizer and configured to generate an aerosol from the vaporizable material.

3. The cartridge of claim 2 , wherein the porous organic substrate includes an air channel disposed therethrough to provide air to the condensation chamber.

4. The cartridge of claim 2 , further comprising:

a cannula in fluid communication with the atomizer and the condensation chamber to deliver the vaporizable material from the atomizer to the condensation chamber.

5. The cartridge of claim 1 , further comprising:

a mouthpiece configured to deliver the aerosol to a user.

6. The cartridge of claim 1 , further comprising:

a first bus bar and a second bus bar, the first bus bar disposed at a first end of the porous organic substrate and the second bus bar disposed at a second end of the porous organic substrate.

7. The cartridge of claim 1 , wherein the cartridge comprises an air channel disposed proximate to the porous organic substrate.

8. The cartridge of claim 1 , further comprising:

a first air inlet in fluid communication with the atomizer, the first air inlet configured to deliver air to the atomizer.

9. The cartridge of claim 1 , further comprising:

a second air inlet in fluid communication with the atomizer, the second air inlet configured to deliver air to the atomizer.

10. The cartridge of claim 1 , wherein the porous organic substrate comprises a plurality of fluid channels configured to provide fluid flow of the vaporizable material.

11. The cartridge of claim 1 , wherein the porous organic substrate has an average pore size diameter from about 5 microns to about 50 microns.

12. The cartridge of claim 1 , wherein the porous organic substrate comprises a surface treatment.
