Ageing of the oxyfluorinated polypropylene surface: evolution of the acid–base surface characteristics with time

In adhesion applications, the rapid ageing of corona discharge pretreated surfaces is a well-known problem. Very often the corona treatment has to be renewed just before the application. Oxyfluorination process presents an interesting alternative to the corona discharge treatment. In this work, the outstanding ageing properties of the oxyfluorinated polyolefin surfaces are described on the basis of acid–base surface characteristics.
