Abstract
A numerical characterization method for the dispersion state of carbon nanotubes based on fractal dimension is invented. In this method, a SEM image of the dispersion state of carbon nanotube is obtained first, and then is binarized by the ImageJ software to extract the boundary of individual carbon nanotubes or carbon nanotubes agglomerates, and thereby calculating the fractal dimension of the processed image with the assistance of the box-count algorithm. The value of fractal dimension represents quantitatively the abundant information contained in the dispersion state of carbon nanotubes, which is capable of realizing the numerical characterization of the dispersion state of carbon nanotubes. The invention quantifies the dispersion state of carbon nanotubes, and provides a powerful strategy for controlling, comparison and prediction of macro-properties of carbon nanotube based composites.
