Abstract

The invention of the present application provides a self-heating sheet-like material for moisture absorption and desorption which includes at least a self-heating layer and an adsorption layer in a laminate thereof, in which the self-heating layer and the adsorption layer are connected in a state in which heat conduction is enabled; a moisture absorption and desorption body formed of this material; and a moisture absorption and desorption device.

First claim

The invention claimed is:

1. A self-heating sheet-like material for moisture absorption and desorption, comprising at least:
a self-heating layer and an adsorption layer in a laminate thereof,
wherein the self-heating layer and the adsorption layer are connected in a state in which heat conduction is enabled,
wherein, regarding a relationship between compressive stress and distortion, the self-heating layer includes
a first region exhibiting plastic deformation, and
a second region exhibiting elastic deformation which appears in a region where a compressive stress is greater than that of the first region.

2. The self-heating sheet-like material for moisture absorption and desorption according to claim 1 , wherein the self-heating layer and the adsorption layer are laminated with an adhesion layer therebetween.

3. The self-heating sheet-like material for moisture absorption and desorption according to claim 1 , wherein the self-heating layer includes an electrode at a free end thereof.

4. The self-heating sheet-like material for moisture absorption and desorption according to claim 1 , wherein the self-heating layer is made of a metallic fiber sintered body.

5. The self-heating sheet-like material for moisture absorption and desorption according to claim 4 , wherein fibers constituting the metallic fiber sintered body include at least stainless steel fibers.

6. The self-heating sheet-like material for moisture absorption and desorption according to claim 2 , wherein the adhesion layer includes at least synthetic fibers.

7. The self-heating sheet-like material for moisture absorption and desorption according to claim 1 , wherein the adsorption layer includes organic fibers, and at least one or more hygroscopic agents selected from organic hygroscopic agents and inorganic hygroscopic agents.

8. A moisture absorption and desorption body comprising the self-heating sheet-like material for moisture absorption and desorption according to claim 1 .

9. A moisture absorption and desorption device, comprising:
an electrical circuit for supplying current to the electrode; and
the self-heating sheet-like material for moisture absorption and desorption or the moisture absorption and desorption body according to claim 3 .
