Abstract

This work has studied crystallization in electric fields of a semiflexible polymer containing poly(ethylene terephthalate) (PET) segments. Electric (E) stimuli were found to either suppress or enhance PET crystallization depending on E-field strength. Over a relatively narrow field range the effect changes from suppression to enhancement of crystallinity. It is suggested that either inter-chain cooperative phenomena or electromechanical effects in the context of nucleation and/or growth may be affecting crystallization. For example, electrical alignment of rigid (mesogenic) segments in the copolymer structure leading to distension of the crystallizable and more flexible PET segments.
