【Abstract】 This article analyzed two important parameters of the microstructure of inorganic nanoparticles filled polymer composites,which were particle size and degree of dispersion. Various approaches to the degree of dispersion of the nanoparticles in polymer composites were introduced,including statistical method,fractal theory,the group sub-theory,and other quantitative methods. With computer graph technology,such dispersion could be quantitatively described by a combination of digital image processing and mathematical method.更多还原
