| 英文摘要: |
| 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. |
