Etching and morphology of poly(vinylidene fluoride)

Abstract

The lamellar structures within spherulites of melt-crystallized poly(vinylidene fluoride) have been examined following the development of an etching technique which allows the study of representative morphologies in this polymer. The banded α-spherulites, which predominate at crystallization temperatures below ∼165°C, are found to be made up of densely packed lamellae with an intrinsically planar habit, whilst the γ-spherulites which develop preferentially at higher temperatures, have a curious architecture in which the lamellae adopt a highly curved “scroll-like” morphology. These observations are discussed in terms of existing models for spherulite banding and non-planar lamellar habits.
