Distributions of CNT/F diameter. Particles were binned according to size along the lower x-axis with frequency on the left y-axis. Additionally, percentage of accumulation is graphed on the right y-axis with the absolute diameter along the upper x-axis. The overlay line was 3 parameter sigmoidal curve of best fit with the point of 50% accumulation indicated with dotted lines. Sizes are for particles in isopropanol suspension
