The adhesion between end-grafted polymer films is studied by coarse grained molecular dynamics simulations. We propose not only the one-end grafted (straight) polymer film but also the both-end grafted (loop) polymer film as a soft adhesive material, and we try to analyze the adhesive properties between them. From our simulations of the straight-straight adhesion system, the separation between the films occurs with forming the fibrils or the cavities. Fibril formation can only be seen at the lower temperature than the glass transition temperature of polymer film. On the other hand, cavity appears at the higher temperature. An adhesion force of the straight-loop system is much stronger than that of the straight-straight system. From our analysis, the difference of the adhesion forces between straight-straight and straight-loop systems can be explained by the mobility of the polymer chains in the films.
