Surface Functionalization with Phosphazenes, Part 3: Surface Modification of Plasma-Treated Polyethylene with Fluorinated Alcohols Using Chlorinated Phosphazenes as Coupling Agents.

Résumé

In this paper, we present a new strategy to functionalize the surface of high-d. polyethylene plates using a cold plasma technique and chlorinated phosphazenes as coupling agents. The clean surface of polyethylene samples was modified by argon plasma treatments to introduce polar groups (e.g., C:O, COOR, OR, OH, etc.); the free hydroxylic functions thus introduced were successively reacted with (NPCl2)3 and (NPCl2)n to graft these substrates onto the surface of the polymer samples through the formation of strong covalent Cl-P-O-HDPE bonds. The residual unreacted chlorines, still present in the phosphazenes, were eventually substituted with alkoxy substituents (e.g., trifluoroethanol and heptadecafluorononanol) according to the classical nucleophilic substitution reaction of both cyclic and polymeric phosphazene materials. In this way, surface features of polyethylene samples could be deeply modified in a rather general and easy way.
