An effective synthesis of polysiloxanes containing mixed functional groups was carried out using consecutive hydrosilylation of two different olefins. With the functionalization of polysiloxanes, we sought to obtain derivatives containing fluoroalkyl groups (with hydrophobic properties) and reactive groups capable of attaching a polysiloxane to the surface. Glycidyl and trimethoxysilyl groups were chosen for the study. All of the obtained derivatives were isolated and spectroscopically characterized. In the next stage of the study, glass plates were modified with functionalized polysiloxanes, both alone and with added silica sol, and their hydrophobic properties were determined by measuring contact angles. From the results, we determined the effect of functionalized polysiloxane structure on the hydrophobic properties of polysiloxane-modified surfaces. (C) 2014 Elsevier B.V. All rights reserved.
