Fractal Dimensions of Carbon Black-Filled Polymers and Elastomers P.2. Fractal Dimensions of Carbon Black-Filled Systems
Fractal dimensions characterizing internal structure and mechanisms of its formation in disperse systems are obtained. The dependencies for individual clusters and image in whole are usually linear in double logarithmic coordinates with angle of inclination between 1.38 and 1.82. All dependencies form two groups, for systems of low (below 10 %) and high (up 15 %) content of fillers, and correspondently, of relatively low (below 1,5) and high fractal dimensions and correspondent to different mechanisms of structure formation («clusters- clusters» and «clusters-particles»). Effect of irradiation (dose from 7 to 60 Mrad) on structure and fractal dimensions is studied. So the connectivity of carbon black aggregates is defined within the framework of fractal dimension concept. Dependence of the fractal dimension of the carbon-filled disperse systems on a preparation method and an external influences is shown.
