ABOUT THE RESULTS OF CALCULATION OF ADSORPTION FOR LIQUID-CRYSTALLINE NANODEMULSIFIERS ON THE BASIS OF THE OXIALKYLENE BLOCK COPOLYMERS
A.A.Gasanov, T.K.Dashdiyeva

 

To calculate the adsorption (Гi) of liquid-crystalline nanodemulsifiers on the basis of poly(ethylene oxide)–poly(propylene oxide) block copolymers on the liquid-gas interface, the Frumkin equation:  Гim[1–exp(Dsi/RTГm)] was used. Correlation equations are proposed for calculating the minimum surface tension of block copolymers at maximum adsorption  (Гm) depending on the molecular mas and the degree of hydroxyethylation of the corresponding oligomers, and a general adsorption isotherm in the coordinates  Гi–(–Δs) is constructed and some comments, interpretations and conclusions based on the results of the research are presented.      

 

Keywords : the Frumkin equation, adsorption at the liquid–gas interface, the liquid-crystalline nano­demulsifiers, surfactants
