Abstract

We present the influence of strain on monolayer graphene transferred on fluorinated ethylene propylene (FEP) substrate. Raman spectroscopy was used to characterize the effect of strain before, during, and after mechanical bending. With the applied strain parameters of 0.77% and 1.05%, significant red shift were observed up to 13 cm^-1 and 33 cm^-1 for the G peak and 2D peak of graphene, respectively. The rate of change of Raman shift per strain was also calculated with values of ‒10.3 cm^-1/% for the G peak and ‒ 30.4 cm^-1/% for the 2D peak. The reported characteristics of graphene on fluorinated ethylene propylene under strain with very good reversibility confirms its excellent flexibility.
