Abstract
Interaction of brushes oriented face-to-face under compression and sub sequent extension is investigated theoretically. Brushes formed by mes ogenic chains with induced stiffness in the liquid-crystalline (LC) st ate are considered. It is shown that the contact between LC brushes co mposed of long folds of grafted chains (FLC structure) leads to interp enetration of brushes and to formation of a combined structure. The br ushes remain combined under the extension of this structure.
