  • Patent number: 9000367
    Abstract: Provided is a method for evaluating a polymer material, wherein the state of dispersion of a filler in a polymer material can be quickly and quantitatively evaluated. The method for evaluating a polymer material which is a polymer material containing the polymer compound and the filler and of which at least an upper surface is a flat surface. The polymer material 1 is cut in a direction at an angle ? of 1 to 60° with respect to the surface of the polymer material using a focused ion beam (FIB) 10, and a smooth surface 1A of the polymer material, formed by the cutting, is then photographed in a direction perpendicular to the smooth surface.
