Mechanical Characterization of Reduced Graphene Oxide Using AFM

Figure 18

This plot compares the reduced Young’s modulus of the sample based on the number of LightScribe reduction cycles. The red points are the average values for the thirty data points taken after each cycle. In order to depict the changing nature of the elastic modulus, these points were fit using a polynomial function shown above. The reduced Young’s modulus increased for the first three reduction cycles before leveling off during the fourth and fifth cycles. The error bars depict the standard deviation of the reduced Young's modulus for the thirty data points taken after each reduction cycle.
