DISPERSION PROPERTY EVALUATION METHOD OF ISLAND PART IN RESIN COMPOSITION, AND DISPERSION PROPERTY EVALUATION DEVICE OF ISLAND PART IN RESIN COMPOSITION

摘要

PROBLEM TO BE SOLVED: To provide a method for speedy and quantitatively evaluating a dispersion property from a microscopic image of a resin composition having a sea-island structure.;SOLUTION: A method for evaluating a dispersion property of an island part from a microscopic image of a resin composition having a sea-island structure comprises the steps of: (A) reading an input image as a grayscale image; (B) generating a low-pass filter processing image from a read image; (C) performing subtraction processing between the read image and the low-pass filter processing image generated in (B), and binarizing the read data by using a threshold; (D) extracting only the island part from binarized image; and (E) calculating a diameter and the dispersion property of the separated island part.;COPYRIGHT: (C)2014,JPO&INPIT
