Title: Using Entanglements to Structure Polymer Melts
Abstract: Entanglements, i.e. topological constraints, are known to dominate the rheological properties of long chain polymer melts and dense solutions. Their properties and consequences led to the generally accepted and well established reptation/tube model, which is at the basis of our understanding of many properties and processes. However, one also can take the approach to use them to manipulate and structure materials, either by avoiding or explicitly using/introducing them. The talk will give a few such examples ranging from melts of non-entangled to very long, highly entangled polymer systems to new entanglement stabilized nanoporous films or topological glasses in active systems. Furthermore, we applied a new data driven approach to determine the glass transition temperature of polymer melts and (ultra) thin films. [1] HP Hsu, KK, Macromolecules 57, 2998 (2024) [2} H. P.
