Three Dimensional Printing of Bioinspired Composite Aerogels for Solar Steam Generation

open access: yesAdvanced Energy and Sustainability Research, Volume 7, Issue 2, February 2026.
Freshwater scarcity demands efficient purification strategies. Inspired by desert grasses, reduced graphene oxide‐doped polyacrylamide aerogels with longitudinal grooves are fabricated via high‐speed three‐dimensional printing and freeze‐drying. The biomimetic design enables dual‐mode water transport, achieving a capillary flow of 2.16 cm in 10 minutes
