Changes in the structure of tethered chain molecules as predicted by density functional approach

Changes in the structure of tethered chain molecules as predicted by density functional approach

We use a version of the density functional theory to study the changes in the height of the tethered layer of chains built of jointed spherical segments with the change of the length and surface density of chains. For the model in which the interactions between segments and solvent molecules are the...

Ми використовуємо один iз варiантiв теорiї функцiоналу густини для вивчення змiн у висотi зв’язаного шару ланцюгiв, утворених з’єднаними сферичними сегментами, iз змiнними довжиною та поверхневою густиною ланцюгiв. Для моделi, у якiй взаємодiї мiж сегментами та молекулами розчинника є такими самими як мiж молекулами розчинника, нами виявлено два ефекти, якi не спостерiгалися у попереднiх дослiдженнях. За певних умов i при низьких поверхневих концентрацiях ланцюгiв висота зв’язаного шару може досягати мiнiмуму. Крiм того, для деяких систем спостерiгається що при збiльшеннi температури висота шару ланцюгiв може зменшуватися. 2011 Article Changes in the structure of tethered chain molecules as predicted by density functional approach/ M.
