Rubbery surface (IMAGE) University of South Florida Caption Illustration of the creation of interfacial transient elastomer domain at the surface via the segmental dynamic gradient, employing representative simulation snapshot (rendered in VMD37). The exponential gradient in activation barriers to relaxation is illustrated by the colour gradient of background beads; a representative chain spanning from the surface to the mid-film is highlighted in yellow. This gradient-spanning strand produces the transient surface rubbery behavior. Credit University of South Florida Usage Restrictions No restrictions.
