Researchers use unique technique to regulate the stiffness of graphene
Researchers from the University of Vienna and Technical University of Vienna have used a unique technique to significantly enhance the stretchability of graphene for the first time by creating an accordion-like ripple effect. This achievement could open up new possibilities for applications that require specific levels of stretchability, such as wearable electronics.
Graphene is notable for its high electrical conductivity but tends to be extremely stiff, as its atoms are arranged in a honeycomb pattern that contributes to this stiffness. It makes sense that removing some atoms from the material along with their bonds would result in reduced stiffness. Scientific research, however, has documented both a modest decline and a notable rise. Scientists have now resolved these contradictions with new measurements. Modern devices were used in the experiments and housed in the same ultra-clean, airless environment. As a result, samples can be moved between the various devices without contacting outside air.
