To study the interaction between polymer and carbon black the filler surface chemistry was modified by means of atmospheric plasma. The treated carbon black was characterized by small angle x-ray scattering. The scattered intensity was analyzed with regard to the fractal dimensions of surface and mass. X-ray photoelectron spectroscopy was used to analyze changes of the surface chemistry and scanning tunneling microscopy to detect changes of active sites on the surface.
