Tung Oil-Based Modifier Toughening Epoxy Resin by Sacrificial Bonds
ACS Sustainable Chemistry and Engineering, 2019 Sacrificial bonds are critical for the excellent toughness of many natural materials. Herein, to toughen epoxy resin, a renewable toughener (TAA) was prepared by incorporating cyano groups into tung oil, which could form sacrificial bonds by the dipole ...

Hierarchical Mechanical Transduction of Precision-Engineered DNA Hydrogels with Sacrificial Bonds
ACS Applied Materials & Interfaces, 2023Engineering the response to external signals in mechanically switchable hydrogels is important to promote smart materials applications. However, comparably little attention has focused on embedded precision mechanisms for autonomous nonlinear response in mechanical profiles in hydrogels, and we lack understanding of how the behavior from the molecular ...

Crack propagation in bone on the scale of mineralized collagen fibrils: role of polymers with sacrificial bonds and hidden length [PDF]
Bone, 2014 Sacrificial bonds and hidden length (SBHL) in structural molecules provide a mechanism for energy dissipation at the nanoscale. It is hypothesized that their presence leads to greater fracture toughness than what is observed in materials without such ...

Creation of Sacrificial Bonds by Viscous Flow Instability
Volume 14: Emerging Technologies; Engineering Management, Safety, Ethics, Society, and Education; Materials: Genetics to Structures, 2014The multiscale structure of spider silk is widely studied because of its superior mechanical properties. Its high tenacity allows the absorption of the kinetic energy of fast and large preys. The mechanism of sacrificial bonds enhances the stretchability and toughness of spider capture-silk.

Do Sacrificial Bonds Affect the Viscoelastic and Fracture Properties of Bone?
Clinical Orthopaedics & Related Research, 2006Sacrificial bonds have been suggested as a toughening mechanism for bone tissue. Ionic bridges formed by divalent calcium ions between collagen molecules have been proposed as candidates for sacrificial bonds. If this mechanism is active at the macroscopic level, we should observe changes in mechanical properties of bone when calcium ions are ...

Bioinspiration & Biomimetics, 2023
Abstract Bioinspired composites exhibit well-defined microstructures, where anisotropic ceramic particles are assembled and bonded by an organic matrix. However, it is difficult to fabricate these composites where both the ceramic particles and organic matrix work together to unlock toughening mechanisms, such as shear dissipation ...

Collagen breaks at weak sacrificial bonds taming its mechanoradicals
2022Abstract Collagen is a force-bearing, hierarchical structural protein important to all connective tissue. In tendon collagen, high load even below macroscopic failure level creates mechanoradicals by homolytic bond scission, similar to polymers.

Instability‐Assisted Direct Writing of Microstructured Fibers Featuring Sacrificial Bonds
Advanced Materials, 2015A 30 μm-diameter thread of poly(lactic acid) (PLA) dissolved in dichloromethane is deposited on top of the eye of a sewing needle. The deposition robot traces a straight line; the helical shape of the thread is due to the liquid rope coiling instability. This instability is used to fabricate microstructured fibers with tailored mechanical properties.
