Reaction/Diffusion Competition Drives Anomalous Relaxation of Vitrimers
Makayla R. Branham-Ferrari, Shinian Cheng, Alexei P. Sokolov +1
Since their discovery in 2011, vitrimers - covalent associative network polymers - have challenged the traditional understanding of soft matter relaxation dynamics: unlike in typic…
Glassy interphases reinforce elastomeric nanocomposites by enhancing percolation-driven volume expansion under strain
Pierre Kawak, Harshad Bhapkar, David S. Simmons
For nearly a century, introduction of nanoparticles to elastomers has yielded extraordinarily tough nanocomposites that are critical to technologies from actuators to tires. The me…
Reducing Data Requirements for Sequence-Property Prediction in Copolymer Compatibilizers via Deep Neural Network Tuning
Md Mushfiqul Islam, Nishat N. Labiba, Lawrence O. Hall +1
Synthetic sequence-controlled polymers promise to transform polymer science by combining the chemical versatility of synthetic polymers with the precise sequence-mediated functiona…
On the origin of heating-induced softening and enthalpic reinforcement in elastomeric nanocomposites
Pierre Kawak, Harshad Bhapkar, David S. Simmons
Despite a century of use, the mechanism of nanoparticle-driven mechanical reinforcement of elastomers is unresolved. A major hypothesis attributes it to glassy interparticle bridge…
