University at Buffalo (UB) and University of Pittsburgh engineers have three-dimensionally (3D)-printed graphene aerogels for water treatment, after addressing scalability and stability issues.
UB's Nirupam Aich said, "The aerogels we've created hold their structure when put in water treatment systems, and they can be applied in diverse water treatment applications."
The researchers infused graphene-derived ink with bio-inspired polymers of polydopamine and bovine serum albumin protein; the augmented aerogels remove contaminants from the water, including heavy metals, organic dyes, and organic solvents.
Aich said the aerogels can be printed in larger sizes, making them usable in large facilities like wastewater treatment plants; they also are reusable.
