Abstract

Perfluoroalkanoyl peroxides such as (C₃F₇COO)₂ have been found to react with polyester film only on the surface. The modified polyester surfaces were characterized by contact angle measurements using a two-liquid phase system and by ESCA spec troscopy. These provided surface free energy values and surface atom content values as a function of reaction time. Perfluoroalkyl groups substituted on the aromatic rings of the polyester surface influenced both the dispersive component γ_s ^d of surface free energy and the polar one γ_S ^p. The surface free energies decreased with the reaction time and reached a plateau at about 1 hour. There was a large decrease in γ_S ^d. Based on the ESCA characterization, the area ratio of the F₁ _s peak to the O₁ _s peak was linearly correlated not only to γ_S ^d but also to γ_S ^p.
