Caracterisation de la surface du polydicyclopentadiene (Poly-DCPD): influence du vieillissement sur le mouillage et l'adhesion de peinture

摘要

This paper deals with the surface study of an industrial polydicyclopentadiene. First, the chemical structure of this polymer is presented. Then the contact 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 polar component. During ageing, surface polarity increases leading to a good paint adhesion and a great affinity for water. However, weak boundary layers formation is possible and discussed in the last part of this paper.
