Bond strength regime dictates stress relaxation behavior† Ipek Sacligil, a Christopher W. Barney, ‡a Alfred J. Crosby a and Gregory N. Tew *a Abstract Reconfigurable polymer networks are gaining interest for their potential applications as self-healing, recyclable, and stimuli-responsive smart materials. Relating the bond strength of dynamic interactions to material properties including stress relaxation time and modulus is crucial for smart material design.

Linking cavitation and fracture to molecular scale structural damage of model networks† Christopher W. Barney, ‡a Ipek Sacligil, a Gregory N. Tew a and Alfred J. Crosby *a Abstract Rapid expansion of soft solids subjected to a negative hydrostatic stress can occur through cavitation or fracture. Understanding how these two mechanisms relate to a material's molecular structure is important to applications in materials characterization, adhesive design, and tissue damage.

Rational mechanochemical design of Diels–Alder crosslinked biocompatible hydrogels with enhanced properties† An important but often overlooked feature of Diels–Alder (DA) cycloadditions is the ability for DA adducts to undergo mechanically induced cycloreversion when placed under force.
