A simplified approach to estimation of changes in the properties of filled polymers operating in aggressive media is proposed. The method of filled polymer image conversion into a binary pattern has been developed that allows special features of the composition to be detected. This, in turn, determines the operational efficiency of the filled polymers in aggressive media. Suitability of the parameter “Minkowski dimension” for estimation of the properties of filled polymers is experimentally substantiated. The technology of transferring the image of the structure of a filled polymer into a binary one is performed using the models UYV and Otsy. This allows us to take into account a wide range of grayscale gradients on the microphotography of the structure of the filled polymers. The appearance of such a spectrum is associated with physicochemical interactions in a multicomponent medium: the interaction “filler–matrix”, a significant change in the degree of compaction of the filler in the matrix, the features of the agglomerated filler existing in the matrix in the form of a cluster of particles of different density, individual particles, etc. Because the material structure can vary significantly, the binarization threshold is calculated automatically for each image separately.
