Hi all,
I am doing investigations on properties of polymer brush when two apposing grafted brush surface slide relatively. I don't know how treat real surface in molecular dynamics and avoid this problem by a method, which defines a hundred times attraction force between Wall(z=0) with grafting end monomers by wall LJ command than other monomer-monomer LJ12/6 potential. Because there is no real surface in my simulation. It looks impossible to slide one grafted brush surface. Could someone give me help or hint to do this project?
I very appreciate help from all.
Best wishes,
Yangpeng Ou
