New paper out in @commsphys.nature.com Glassy polymer films swell over hours, but molecules inside move on seconds. Local diffusivity exceeds macroscopic transport. Why? Transient elastic cages. Macroscopic expansion needs collective cage rearrangements. 👉 www.nature.com/articles/s42...

The more stressed a polymer film is, the harder it is to relax. Activation barriers are set by the stress itself — opposite to classical plasticity. New paper in PRL with a great team across IIT Bombay, ULB Brussels, Dartmouth & IIT Kanpur 🧵 🔗 doi.org/10.1103/k28h...

While concrete tetrapod blocks invite the flow of small water molecules into their arms to protect shorelines, tetrapod nanoparticles in long-chain polymers create space that restricts polymer movement, promoting flow by inducing entropic frustration from chain packing.
