Abstract—
A comparative study of nanosystems based on the biogenic element selenium in the zero-valent form (Se0) and amphiphilic molecular brushes (graft-CP) with a hydrophobic polyimide backbone and hydrophilic side chains of polymethacrylic acid is performed using atomic force microscope, UV-vis spectroscopy, and dynamic light scattering. It is shown that the morphological and spectral characteristics of Se0/graft-CP nanostructures can be controlled by varying the degree of polymerization m of the side chains of amphiphilic molecular brushes. The effect of the nature of the solvent (water, dimethylformamide, and chloroform) on the morphology of thin graft-SP films on mica is shown by the example of a free (not loaded with Se0 nanoparticles) amphiphilic molecular brush of graft-SP with a specified degree of polymerization of the side chains (m = 270).
