摘要：

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 spectroscopy. 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 gamma(Sd) of surface free energy and the polar one gamma(Sp). The surface free energies decreased with the reaction time and reached a plateau at about 1 hour. There was a large decrease in gamma(Sd). Based on the ESCA characterization, the area ratio of the F1s peak to the O1s peak was linearly correlated not only to gamma(Sd) but also to gamma(Sp).
