Novel textured coatings made from graphene can act as ultrastretchable barriers to stop chemicals and other molecules from passing through, according to new research from the Brown University Superfund Research Program Center. The authors suggest these novel films could be used to create multifunctional fabrics and responsive devices, including personal monitoring equipment, wearable electronics, and soft robotics.
The research team used graphene nano-sheets that can change shape by folding and unfolding to mimic a more elastic behavior, which improves upon traditional approaches that create a material that is quite stiff and cracks easily. The stretchable technology also can function as a sensor to detect certain chemicals and to act as either an impassible or selective barrier. These characteristics will make the material useful for a variety of future cutting-edge applications.
