Air-permeable hydrogels through viscoelastic phase separation of aerogels
Nature, Published online: 08 July 2026; doi:10.1038/s41586-026-10712-3 Viscoelastic phase separation is used to fabricate non-collapsible, air-rich networks in high-water-content hydrogels containing silica aerogel beads, allowing air to permeate through the material and enabling a tenfold increase in oxygen permeability over pristine hydrogels.
