ABSTRACT
The changes in the surface state of a polymer that occur when the surrounding medium is abruptly changed might be described as the process that leads to equilibration of surface states at the interface with the new contacting medium. When contact is established between two different materials, the surface states of the contacting materials begin to equilibrate. In the case of polymer immersed in water, the surface state of the polymer and the surface state of the water, which is recognized as the vicinal water in biological science, start to establish the equilibrium as soon as contact is made.
