Abstract
The present work is devoted to studies of the rheological properties of sol–gel systems based on tetraethoxysilane by the falling ball method developed by F. Hoppler. The systems under study were modified by organic polyols of linear, branched, and hyperbranched structures and inorganic boron and gadolinium dopants. The parameters of viscosity and strength of the network of the formed organic-inorganic composite, which are important characteristics of sol–gel systems properties, have been presented. The data characterizing the range of permissible concentrations of organic components introduced into a system to improve the synthesized films properties have been demonstrated.
