A paper material having water sorption capacity and method for forming the same is provided. The paper material may be formed from a mixture including thermoplastic organic fibers, micro porous particles, and hydroscopic salt or a mixture including organic fibers, titania or a transition alumina micro porous particles, and a hydroscopic salt. The paper may be produced by forming an aqueous slurry, including organic fibers and micro porous particles, mixing the slurry, feeding the mixed slurry into a paper making apparatus thereby forming a sheet, contacting the sheet with a solution containing an amount of hydroscopic salt, and drying the hydroscopic salt containing solution.

The invention claimed is: 1. A paper material having water sorption capacity comprising: a calendared sheet formed from a mixture including thermoplastic organic fibers, micro porous particles, and a hydroscopic salt; said hydroscopic salt is lithium chloride, lithium bromide, or combinations thereof. 2. A paper material as set forth in claim 1 wherein said micro porous particles are titania or a transition alumina. 3. A paper material as set forth in claim 1 wherein said particles are gamma alumina. 4. A paper material as set forth in claim 1 wherein said sheet being substantially impervious to the flow of air therethrough. 5. A paper material as set forth in claim 1 wherein said hydroscopic salt is lithium chloride. 6. A paper material as set forth in claim 1 wherein said thermoplastic organic fibers are polyvinyl alcohol, polyethylene, or bicomponent fibers made from two of the above fibers. 7. A paper material as set forth in claim 1 wherein a substantial amount of the hydroscopic salt is captured in the pores of the micro porous particles. 8. A paper material having water sorption capacity comprising: a calendared sheet formed from a mixture including organic fibers, titania or a transition alumina micro porous particles, and a hydroscopic salt; said hydroscopic salt is lithium chloride, lithium bromide, or combinations thereof. 9. A paper material as set forth in claim 8 wherein organic fibers are thermoplastic. 10. A paper material as set forth in claim 9 wherein said fibers are polyvinyl alcohol, polyethylene, terathialate, acrylic polyethylene terathialate, or bicomponent fibers made from two of the above fibers. 11. A paper material as set forth in claim 8 wherein said sheet being substantially impervious to the flow of air therethrough. 12. A paper material as set forth in claim 8 wherein said hydroscopic salt is lithium chloride. 13. A paper material as set forth in claim 8 wherein said particles are gamma alumina. 14. A paper material as set forth in claim 8 wherein a substantial amount of the hydroscopic salt is captured in the pores of the micro porous particles. 15. A plate type heat exchanger comprising: a substrate; said substrate formed from a paper material having a water sorption capacity; and a calendared sheet formed from a mixture including thermoplastic organic fibers, micro porous particles, and a hydroscopic salt; said hydroscopic salt is lithium chloride, lithium bromide, or combinations thereof. 16. A plate type heat exchanger as set forth in claim 15 wherein a substantial amount of the hydroscopic salt is captured in the pores of the micro porous particles. 17. A plate type heat exchanger comprising: a substrate; said substrate formed from a material having water sorption capacity; and a calendared sheet formed from a mixture including organic fibers, a transition alumina or titania micro porous particles, and a hydroscopic salt; said hydroscopic salt is lithium chloride, lithium bromide, or combinations thereof. 18. A plate type heat exchanger as set forth in claim 17 wherein a substantial amount of the hydroscopic salt is captured in the pores of the micro porous particles. 19. A method for forming a paper material having water sorption capacity comprising: forming an aqueous slurry, including organic fibers and micro porous particles; mixing said slurry; feeding said mixed slurry into a paper making apparatus, thereby forming a sheet; contacting said sheet with a solution containing an amount of hydroscopic salt, said hydroscopic salt is lithium chloride, lithium bromide, or combinations thereof; drying said hydroscopic salt containing solution and calendaring said sheet. 20. A method as set forth in claim 19 further including adding wood pulp to said slurry. 21. A method as set forth in claim 19 further including slitting said sheet containing hydroscopic salt, thereby forming multiple sheets. 22. A method as set forth in claim 21 further including feeding at least one of said slit sheets into a corrugation machine whereby said at least one sheet is corrugated. 23. A method as set forth in claim 22 further including placing said corrugated sheet in contact with another sheet, heating said corrugated sheet and the other sheet whereby the corrugated sheet becomes adhered to the other sheet. 24. A method as set forth in claim 23 wherein said corrugated sheet is adhered to the other sheet without the use of an adhesive. 25. A method as set forth in claim 19 wherein said micro porous particles are titania or a transition alumina. 26. A method as set forth in claim 19 wherein said organic fibers are thermoplastic and are taken from the group consisting of polyvinyl alcohol, polyethylene, terathialate, acrylic polyethylene terathialate, or bicomponent fibers made from two of the above fibers. 27. A method as set forth in claim 19 wherein the amount of hydroscopic salt in said solution containing said hydroscopic salt is 8.3% wt, or less.
