Analysis of the Structure of the Adsorbed Polymer Layers on the Surfaces of Metal Oxide Microparticles Using Digital Image Processing

“…To obtain data on an increase in the quantity of adsorbed polymer per unit particle surface area, we calculated the ratios of the particle surface area before and after mechanical treatment and compared them with the ratio of the saturation concentrations [6,7]. Since the particles are spherical, the ratio of the total particle surface areas before and after mechanical acti- Relative polymer concentration, % vation can be represented as the ratio of the average particle diameters (see Table 1).…”

“…The absence of polymer stabilizers of mechanical activation was shown to coarsen particles (associates of particles are dispersed to initial particles with activated surface during mechanical action, and these particles coagulate rapidly and transform into agglomerates). In the presence of a polymer, dispersion is "fixed" due to the formation of protective adsorption-solvate polymer layers [1][2][3][4][5][6][7].…”
