Abstract:
      The dispersion of carbon black in styrene-butadiene rubber（SBR） vulcanizates was obtained by high-resolution transmission electron microscope（HR-TEM），and the position of zinc oxide particles in the HR-TEM image was located combined with the mapping spectrum. The binary image containing only carbon black particles was then obtained by algebraic operations between images based on the image processing theory using Matlab. Finally，a quantitative evaluation method of carbon black dispersion in HR-TEM images was established based on the fuzzy comprehensive evaluation theory，and the determination of the carbon black dispersion grade was achieved. The results showed that，compared with the traditional manual identification method，the method based on image processing could achieve quantitative analysis of the dispersion status of carbon black in SBR vulcanizate，and this method improved the accuracy and reliability of the determination of carbon black dispersion grade to a certain extent.
