Mechanical Characterization of Reduced Graphene Oxide Using AFM

Figure 16

This plot compares the stiffness 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 stiffness, these points were fit using a polynomial function shown above. The error bars depict the standard deviation of the stiffness for the thirty data points taken after each reduction cycle.
