Abstract
A detailed study of the alkaline degradation of PVdF has been carried out b y X-ray photoelectron spectroscopy, secondary ion mass spectrometry and Ram an spectroscopy to determine the composition of the modified layer. The stu dy indicates the formation of a surface layer consisting of conjugated C=C bonds and the inclusion of oxygen functionalities on treatment. A mechanism for this degradation process is proposed. This includes the formation of t he polyene structure followed by hydroxide attack to yield hydroxyl and car bonyl groups.
