Researchers create 3D printed, biodegradable, color-changing conductive material from cellulose

An elastic material that changes color, conducts electricity, can be 3D printed and is also biodegradable? That is not just scientific wishful thinking: Empa researchers from the Cellulose & Wood Materials laboratory in Dübendorf have produced a material with these exact properties on the basis of cellulose and carbon nanotubes. The work is published in the journal Advanced Materials Technologies.
