Abstract

Adhesion between two polymer films consisting of one-end grafted polymer is studied by coarse-grained molecular dynamics simulations. We have discussed the effect of topology of polymers in our previous study. In this study, we study the effect of the grafted density. From our simulations, we can observe three kinds of separations; fibril, cavity, and brittle separated structures. Brittle separation pattern is only observed at the case of higher grafted density, though fibril and cavity separations can be observed at the cases of lower grafted density. Maximum adhesion stress can be seen at the brittle separation, and maximum adhesion energy can be seen at the cavity separation. Detail of our results will be reported in the session.
