Three Dimensional Printing of Bioinspired Composite Aerogels for Solar Steam Generation

Advanced Energy and Sustainability Research, EarlyView.
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
