Abstract: An atmospheric water generator apparatus extracts water vapor from low humidity air using hygroscopic materials that alternate between hydrophilic and hydrophobic states based on temperature. A composite material of hygroscopic and thermoresponsive polymers facilitates water vapor absorption and desorption. The composite material is structured to maximize surface area. The apparatus includes a chamber with a thermal management system for absorption and desorption phases. The chamber can open, permitting air intake and exhaust during the absorption phase. The chamber can close, preventing external air flow during the desorption phase. Fans may assist air flow during both phases. The composite material is heated during the desorption phase. When heated, the composite material releases water vapor, which is then condensed and collected. Condensation may be aided by hydrophilic materials, hydrophobic materials, and a cooled surface.
