3D-Printed CNT/rGO–PALF Aerogels for Solar Interfacial Evaporation

Access to clean water is a critical global challenge, with billions facing water scarcity or contamination. This project aims to develop a sustainable water purification system that uses solar energy to convert contaminated or salty water into clean water, offering a low-cost, off-grid solution for rural and resource-limited communities. The system will use solar-driven interfacial evaporation (SDIE) with advanced 3D-printed aerogels made from carbon nanotubes (CNT), reduced graphene oxide (rGO), and pineapple leaf fiber (PALF). These materials provide excellent sunlight absorption, strong resistance to fouling and UV damage, and a biodegradable structure.

By combining these materials in a 3D-printed design, the project will improve water evaporation efficiency and long-term stability, making the system more practical for real-world wastewater treatment. Collaboration between Universiti Tun Hussein Onn Malaysia and the University of Waterloo will strengthen research ties, share knowledge, and offer valuable training for students and researchers at both institutions. This joint work will enhance both universities’ expertise in green technology and sustainable water treatment, supporting their missions to deliver innovative solutions for clean water access and address global environmental challenges.
