Abstract

We investigated the effect of a cyclic chain structure on the wear resistance of polymer brushes via coarse-grained molecular dynamics simulations. Friction simulations were performed for cyclic and linear polymer brushes, and the former was found to exhibit superior wear resistance. The cyclic structure suppressed the interpenetration of the polymer chain at the sliding interface, thereby reducing the frictional force and improving the wear resistance for the cyclic polymer brush.
