Researchers Develop a New Process of 3D Printing Graphene Aerogels
Written by AZoNanoApr 15 2021
Graphene excels at removing contaminants from water, but it s not yet a commercially viable use of the wonder material.
That could be changing.
In a recent study, University at Buffalo engineers report a new process of 3D printing graphene aerogels that they say overcomes two key hurdles scalability and creating a version of the material that s stable enough for repeated use for water treatment. The goal is to safely remove contaminants from water without releasing any problematic chemical residue, says study co-author Nirupam Aich, PhD, assistant professor of environmental engineering at the UB School of Engineering and Applied Sciences.

The researchers at the University at Buffalo, New York have used a proof-of-concept direct ink writing 3D printing technique and subsequent freeze-drying to prepare graphene-biopolymer aerogels for water treatment.
“The goal is to safely remove contaminants from water without releasing any problematic chemical residue,” said study co-author Nirupam Aich, PhD, assistant professor of environmental engineering at the UB School of Engineering and Applied Sciences. “The aerogels we’ve created hold their structure when put in water treatment systems, and they can be applied in diverse water treatment applications.”
