Abstract:Atomic force microscopy (AFM), as a material characterization technique, has been widely used in the study of microstructure of elastomer materials. In this paper, the working principle and working modes of AFM were reviewed. In addition, the recent research progress of AFM applied to the interface structure, filler dispersion and stretching process of elastomeric composites was systematically introduced. The relevant research methods and results were summarized. Finally, the research prospect of AFM in the field of microstructure of elastomer composites was forecasted, which provided theoretical guidance for quantitative characterization of the microstructure of elastomer composites in the future.
