Abstract
A material for moisture removal and/or water harvesting from air may include a hydrophilic material containing micropores and a low water activity material confined within the micropores of the hydrophilic material. Apparatuses containing such materials and methods for moisture removal and/or water harvesting from air by using such materials are also described.
Claims20
A material for moisture removal and/or water harvesting from air, comprising:
- a hydrophilic material containing micropores, wherein the hydrophilic material is selected from the group consisting of silica, zirconium dioxide, zinc oxide, titanium oxides, doped titania, silver titanate, ceramic materials, inorganic polymers, organic polymers and plasma treated polymers;
- and
- a low water activity material confined within the micropores of the hydrophilic material,
- wherein the micropores of the hydrophilic material have a L/D aspect ratio greater than 2.
