Elucidating the Role of Heteroatoms in Hypercrosslinked Polymer Adsorbents for Atmospheric Water Harvesting

Key Points

• To investigate the impact of heteroatoms on the efficacy of hypercrosslinked polymers in capturing atmospheric water.
• Systematic introduction of nitrogen, oxygen, sulfur, or sulfone moieties into hypercrosslinked polymer backbones.
• Characterization of the modified polymers for their adsorption properties.
• Comparison of adsorption capacities for water vapor.
• Enhanced adsorption capacity observed in polymers with nitrogen and oxygen moieties.
• Specific interactions with water molecules identified as key performance drivers.
