Polydicyclopentadiene (poly-DCPD) surface characterization: Surface aging effect on wettability and paint adhesion

This paper deals with the surface study of an industrial polydicyclopentadi ene. First, the chemical structure of this polymer is presented. Then the c ontact angle measurements between the solid surface and various liquids are discussed. Surface energy value is 48 mJ/m(2) for total energy and 3mJ/m(2) for the po lar component. During ageing, surface polarity increases leading to a good paint adhesion and a great affinity for water, However, weak boundary layer s formation is possible and discussed in the last part of this paper.
