Thin composite polymethyl methacrylate films with silicon dioxide nanoparticles

Techniques for the formation of thin polymer films based on polymethyl methacrylate and composite coatings with silicon dioxide nanoparticles on glass and silicon substrates have been optimised, and their structural characteristics have been studied by atomic force microscopy. The effect of the introduction of silicon dioxide nanoparticles and their content on the structure and wettability of the formed composite coatings is described. Experimental data are presented which prove that the incorporation of SiO2 nanoparticles into the structure of the polymethyl methacrylate polymer matrix leads to changes in the roughness parameters of the coatings.
