Anisotropic Nanoparticle Rejamming Triggers Thermodynamic Cavitation in Elastomer Nanocomposites
Harshad Bhapkar, Pierre Kawak, David S. Simmons
Nanoparticles can dramatically reinforce elastomers while paradoxically causing cavitation at lower strains. Despite decades of research, the microscopic origin of this behavior ha…
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…
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…
Central role of filler-polymer interplay in nonlinear reinforcement of elastomeric nanocomposites
Pierre Kawak, Harshad Bhapkar, David S. Simmons
Nanoparticles can greatly enhance the mechanical response of elastomeric polymers essential to a wide range of applications, yet their precise molecular mechanisms of high-strain r…
