3D‐Printed Hydrogels and Aerogels for Water Treatment and Energy Storage Applications

Recently, three-dimensional (3D) printing has become a research focus point and evolved as powerful tool for manufacturing complex objects advanced technology platform designs. Herein, we review the current state-of-the-art 3D-printed hydrogels aerogels wastewater treatment energy storage applications. Several 3D methods such direct ink writing, digital light processing, fused filament fabrication have been discussed. Among these, writing is most employed technique aerogels. We systematically investigated important results of several adsorption, photocatalysis, membrane filtration, desalination treatment, supercapacitors, batteries in Finally, conclude our understanding with prospect future opportunities this field using In summary, fundamental knowledge critical assessment key literature on their applications water will provide guidance studies smart materials waste management aspects sustainability.
