Abstract:
1. 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): (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).
