Surface functionalization with phosphazenes. V. Surface modification of plasma-treated polyamide 6 with fluorinated alcohols and azobenzene derivatives through chlorinated phosphazene intermediates.

Résumé

In this article, we describe the synthesis and characterization of surface-modified polyamide-6, using polydichlorophosphazene and hexachlorocyclophosphazene as coupling agents. The solid surface of this polymer was modified first by the introduction of polar functions (C=O, OH, OR, COOH, COOR, etc.) with a cold plasma technique, then by the treatment of the alc. groups on the surface with (NPCl2)n and (NPCl2)3 to graft these substrates through the formation of strong covalent P-O-C bonds, and eventually by the substitution of the residual chlorines on the polyamide-6 surface with different types of fluorinated alcs. (2,2,2-trifluoroethanol and heptadecafluorononanol) and with 4-hydroxyazobenzene. Contact-angle measurements, together with XPS and UV-visible spectroscopy techniques, support the occurrence of these surface-functionalization reactions.
