Method for analyzing rubber compound with filler particles

摘要

A method for analyzing rubber compound including a rubber component and filler particles, comprises: a STEM image acquiring step in which, by the use of a scanning transmission electron microscope (STEM), data of STEM images of the rubber compound are acquired; and a researching step for researching the STEM images or secondary information based on the original data of STEM images; wherein in the STEM image acquiring step, the focal point of the scanning transmission electron microscope is set in a thickness center region of a specimen of the rubber compound.
