According to the researchers, led by Hongzhi Wang and Qinghong Zhang, they developed the paper to address limitations on current “polymer active materials.”
The paper moves because some parts of it are hydrophobic and other regions of it are hydrophilic, this puts strain on the paper that causes it to fold, reports Chemical & Engineering News. Heat from an IR laser can be used to amplify the strain.
Devices made out of the graphene paper can, “adopt predesigned shapes, walk, and turn a corner,” and could possibly be used for sensing, artificial muscles, and robotics. — Bea Montenegro/TJD, GMA News
