| Abstract: | Study of the chain relaxation at the polymer surfaces is a hot point in physics of the polymer condensed state.The polymer chains at the surfaces have the distinct mobile behaviors different from those of the bulk,which induce the special properties of the polymer surfaces,such as the environmental responsiveness and surface viscoelasticity.The advances in study of the polymer surface relaxation behaviors in the nearest twenty years were reviewed,including the methodologies based on different characterization techniques,the specialty of the surface relaxation behaviors and the factors affecting the surface relaxation behaviors.Our understanding on the polymer surface relaxation behaviors will be deepened as the development and application of the new characterization techniques. |
