The Optimum Dispersion of Carbon Nanotubes for Epoxy Nanocomposites: Evolution of the Particle Size Distribution by Ultrasonic Treatment

Figure 18

Agglomerate size data at 20% and 40% amplitude were fitted using (4) (dotted lines), and (7) (solid lines). Marquardt non-linear curve fit did not give converging results for the other two datasets. Eqution (7) was plotted with estimated parameters as a guide for data from the bath sonicator. Amplitudes 10% (■), 20% (▲), 40% (●), bath sonicator (♦).
