Abstract

A system can employ an atmospheric water harvesting (AWH) composite. The AWH composite can include a foam and a plurality of deliquescent particles. The foam can include an organic polymer. The foam can have pore size of at least 1 μm. The deliquescent particles can be disposed on internal surfaces of the foam. The deliquescent particles can be formed of one or more hygroscopic materials. In operation, the AWH composite can be provided in an atmosphere having a relative humidity, such that water in the atmosphere is captured by the AWH composite. The captured water can be released by heating the AWH composite.
