In this work we study kinetics of adsorption process and structure of nanolayers formed by a new oligoperoxide with dihydroantracene units. It is shown that the structure of oligoperoxide nanolayer adsorbed on a glass surface depends on the concentration of polymer in aqueous solution and the duration of adsorption process. The adsorption isotherm curves reveal a complicated time dependences explained by changes occurring in the conformation of macromolecules on the solid surface. A stable equilibrium of the structure of adsorption nanolayers is reached in a few tens of minutes.

Анотація. У роботі досліджено структуру та кінетику формування наношарів нового дигідроантраценовмісного олігопероксиду в процесі адсорбції. Встановлено залежність структури адсорбованого наношару від концентрації полімеру в розчині і тривалості процесу адсорбції. Кінетичні ізотерми адсорбції мають складний характер, що пояснюється змінами конформації макромолекул на повер-хні твердого тіла. Час встановлення стійкої рівноваги в структурі адсорбційного наношару становить декілька десятків хвилин.
