Abstract:Structure-rheology relationships have been studied on polymer blends, block copolymers and polymer composites. The excess shear stress of polymer blends with droplet/matrix structure after application of a large step shear strain is predicted fairly well by the Doi-Ohta theory, when the interface tensor describing the anisotropy of the interface can be evaluated from observation of the deformed interface shape. The frequency dependence of storage G' and loss moduli G" of polymer blends with bicontinuous struct… 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.
