Abstract

Claims (15)

1. A laminate aerosol generating material, wherein the material comprises a carrier layer, a layer of aerosol-forming amorphous solid attached to the carrier layer, and a porous layer attached to the amorphous solid layer;

wherein the carrier layer and porous layer are disposed on opposing sides of the amorphous solid layer.

2. A laminate aerosol generating material according to claim 1 , the porous layer comprises paper, polymeric fibres, open cell foam, ceramic or zeolites.

3. A laminate aerosol generating material according to claim 1 , wherein the carrier comprises one or more materials selected from metal foil, paper, carbon paper, greaseproof paper, ceramic, carbon allotropes, plastic, cardboard, wood or combinations thereof.

4. An aerosol generating assembly comprising the laminate aerosol generating material according to claim 1 and a heater configured to heat but not burn the aerosol generating material.

5. An aerosol generating assembly according to claim 4 , wherein the assembly is a heat-not-burn device.

6. An aerosol generating assembly according to claim 4 , wherein the assembly is an electronic tobacco hybrid device.

7. An aerosol generating article for use in an aerosol generating assembly, the article comprising the laminate aerosol generating material according to claim 1 .

8. A method of making laminate aerosol generating material comprising:

attaching a layer of aerosol-forming amorphous solid to a carrier layer, and attaching a porous layer to the amorphous solid layer;

wherein the carrier layer and porous layer are disposed on opposing sides of the amorphous solid layer.

9. A method according to claim 8 , the method comprising (a) forming a slurry comprising components of the amorphous solid or precursors thereof, (b) applying the slurry to the carrier, and (c) setting the gel and (d) drying the gel to form an amorphous solid.

10. A method according to claim 9 , wherein the porous layer is disposed on the surface of the slurry prior to (c) of setting the gel.

11. A method according to claim 9 , wherein (c) comprises the addition of a setting agent to the slurry.

12. A laminate aerosol generating material according to claim 1 , wherein the carrier layer abuts the amorphous solid layer, which in turn and the amorphous solid layer abuts the porous layer.
