COF Gel-Based Hygroscopic Composites — LiCl Confinement Without Leakage (Zheng et al., Water Research 2025)
confidence: medium
Source: https://doi.org/10.1016/j.watres.2025.125052
Source: Water Research (Nov 2025), paywalled; abstract-level. Credibility: Medium-high — top-journal peer-reviewed primary data; AWH context, cooling transfer inferred.
Key numbers
- 55 wt% LiCl loading, no leakage, no matrix swelling (rigid COF gel vs hydrogel hosts).
- 3.7 g/g max uptake; 1.2 g/g/h rate; 6 solar cycles/day outdoors at 60% RH.
Transfer to cooling
Same physics/failure modes as composite-salt-sorbents; complements the SJTU encapsulated-composite route (Cui/Wang, Energy 2024: 50 °C-driven chiller, SCP 102 W/kg, ~2× silica gel at those temperatures — DOI 10.1016/j.energy.2024.133391, pre-window context). Together they mark confinement engineering as the composite-sorbent frontier.
