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 α 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.
Claims4
A method for evaluating a polymer material containing a polymer compound and a filler, of which at least an upper surface is a flat surface, the method comprising:
- cutting the upper surface of the polymer material in a direction at an angle of 1 to 60° with respect to the upper surface of the polymer material using a focused ion beam;
- and then photographing a smooth surface of the polymer material, formed by the cutting, in a direction perpendicular to the smooth surface, and
- wherein the filler is at least one selected from the group consisting of silicas, carbon blacks, and inorganic compounds represented by the following formula (I):
- mM.xSiOy.zH2O (I)
- (wherein M is at least one selected from metals selected from the group consisting of aluminum, magnesium, titanium, calcium and zirconium, oxides or hydroxides of the metals and hydrates thereof, or carbonates of the metals;
- and m, x, y, and z are an integer of 1 to 5, an integer of 0 to 10, an integer of 2 to 5, and an integer of 0 to 10, respectively).
