Abstract:The shear piezoelectricity of polylactide (PLA) depends on the chain orientation, crystallinity, and optical purity, but their combined influence on the piezoelectric properties has never been studied. This work examines the effect of optical purity on the piezoelectric chain morphology induced by cold-drawing and heat treatment. Moreover, the influence of force and frequency during dynamic mechanical activation on the piezoelectric response of PLA was studied. The results of this work present for the first ti… Show more
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
