Elongated ring polymers get tied up in knots
News Article, October 13, 2022 • Many polymer liquids flow easily when stretched gently but become viscous and solid-like when stretched rapidly. This phenomenon, known as strain hardening, happens when the liquid is deformed so fast that individual polymer chains become elongated at the molecular scale. Understanding the physics of strain hardening is important for a range...
