Abstract

In the present work, micrographs of polymer nanoparticles were studied by parameter image intensity to study their physical and chemical properties and the process of formation of polymer droplets. The use of digital image processing methods according to the parameter of the intensity of the image makes it possible to accurately determine the shape and size of particles, the dynamics of the polymer deposition process under study. In the study of dispersed systems of polymer nanodroplets, decoding by means of digital processing of microphotographs revealed the contours of the boundaries of the nanoparticles and the accompanying layer, calculated their area and estimated linear dimensions. Investigating changes in the intensity of the image of the layer of the polymer for various experimental conditions, allowed to reveal the principles of changes in density in this layer. Digital processing of photographs of particles of polymer by the criterion of intensity (brightness) of the image made it possible to obtain data on the parameters of nanoparticles, which are in good agreement with the results obtained using the instrumental methods of physical and chemical analysis.
