Sacrificial Mechanical Bond is as Effective as a Sacrificial Covalent Bond in Increasing Cross-Linked Polymer Toughness [PDF]

Journal of the American Chemical Society, 2023
Sacrificial chemical bonds have been used effectively to increase the toughness of elastomers because such bonds dissociate at forces significantly below the fracture limit of the primary load-bearing bonds, thereby dissipating local stress.

Hydrogels toughened by biominerals providing energy-dissipative sacrificial bonds [PDF]

Journal of Materials Chemistry B, 2020
Inspired by bone tissues, we mineralized low crystalline hydroxyapatite (HAp) particles in double network (DN) hydrogels, and we observed that the HAp minerals toughen the gels. The contribution of dissipated energy from HAp minerals was over 500% higher

Toughening elastomers with sacrificial bonds and watching them break [PDF]

Science, 2014
Elastomers are widely used because of their large-strain reversible deformability. Most unfilled elastomers suffer from a poor mechanical strength, which limits their use.

Sacrificial bonds and hidden length: unraveling molecular mesostructures in tough materials [PDF]

Biophysical Journal, 2006
Sacrificial bonds and hidden length in structural molecules and composites have been found to greatly increase the fracture toughness of biomaterials by providing a reversible, molecular-scale energy-dissipation mechanism.

Sacrificial bonds enhance toughness of dual polybutadiene networks

Polymer, 2017
A new dual network elastomer is developed that consists of polybutadiene crosslinked with both permanent and transient bonds. The transient network is formed by the association of urazole groups that are randomly attached to the polymer backbone ...

Metal–Ligand Interactions and Salt Bridges as Sacrificial Bonds in Mussel Byssus-Derived Materials [PDF]

Biomacromolecules, 2016
The byssus that anchors mussels to solid surfaces is a protein-based material combining strength and toughness as well as a self-healing ability.

Metal–Ligand Complexes as Dynamic Sacrificial Bonds in Elastic Polymers

Macromolecules, 2022
The chemical modification of technical rubbers to fine-tune their properties is a subject of current interest. Here, we report a facile approach for the straightforward introduction of non-covalent cross-links based on metal–ligand complexes into styrene-

Embedded proteins and sacrificial bonds provide the strong adhesive properties of gastroliths

Nanoscale, 2012
The adhesive properties of gastroliths from a freshwater crayfish (Cherax quadricarinatus) were quantified by colloidal probe atomic force microscopy (AFM) between heavily demineralized gastrolith microparticles and gastrolith substrates of different ...
