Abstract
In this work, the wetting ability of the VK phytopreparation and its associates with polyelectrolytes were studied. VK is a complex of biologically active substances (BAS) isolated from Alhagi (family -Fabacae Lindi). The association of a phytopreparation with Polyhexamethylene guanidine hydrochloride (PHMG) occurs due to hydrogen bonds stabilized by hydrophobic interactions of non-polar groups of a polyelectrolyte. Therefore, intensive compaction of macromolecules of the phytopreparation-PHMG complex takes place and the viscosity of the mixture of solutions is greatly reduced. In this case, the surface of the complex will be enriched (saturated) with polar groups, which causes a decrease in the contact angles of solutions of associates compared with the phytopreparation, as well as the fraction of the occupied surface. PHMG and phytopreparation have a weak hydrophilizing effect on the surface of Teflon. The composition of the reagents under consideration suggests a certain imbalance in the hydrophilic and lipophilic properties of macromolecules towards the polar part. The low values of the surface fraction and their associates show that a sufficiently rarefied adsorption layer forms on the surface of quartz and Teflon.
