Researchers from North Carolina State University and the University of Texas released a new study showing how strong the interface is between graphene and a stretchable substrate. This can lead to new flexible/stretchable electronics.
The new study shows how much the material can be deformed before the the interface to the graphene fails. The researcher also demonstrated a useful approach to make graphene-based, stretchable devices by ‘buckling’ the graphene.
The researchers used a single graphene sheet and applied it to a polymer substrate. The substrate was stretched, and using a spectroscopy technique the researchers monitored the strain at various points in the graphene. At a certain point, when the substrate was stretched too much, the graphene began to stretch more slowly and slide on the surface.
