AbstractEven though nanocomposites have provided a plethora of routes to increase stiffness and strength, achieving increased toughness with suppressed catastrophic crack growth has remained more challenging. Inspired by the concepts of mechanically excellent natural nanomaterials, one‐component nanocomposites were fabricated involving reinforcing ...

Reinforcement of polysiloxane/silica elastomer composite by introduction of sacrificial bonds
Journal of Applied Polymer Science, 2017ABSTRACTIt is a challenge to improve tear strength of silicone rubber, especially at high filler loading circumstances. A method is offered here to introduce sacrificial bonds into the system. In particular, amide group was introduced onto the phenyl group of monomer methyl phenyl cyclosiloxane ( first, and this functionalized monomer ( was further ...

Journal of Polymer Science, 2022
AbstractDue to the improvement of strength and toughness at the same time, construction of reversible sacrificial bond network has attracted extensive attention to realize the high performance and functionalization of rubber materials. However, the research on the viscoelastic behavior of vulcanized rubber with reversible sacrificial bond network lags ...

Characterizing the naturally occurring sacrificial bond within natural rubber
Polymer, 2019Abstract The influence of protein on the superior properties of NR was analyzed in term of sacrificial bonds. It was found that the presence of the naturally occurring sacrificial bond provided by protein increases the tensile strengthen and toughness, furthermore prolongs the fatigue life of NR.

Generalization of the sacrificial bond principle for gel and elastomer toughening
Polymer Journal, 2017Although conventional polymer gels are known as mechanically weak materials, their fracture toughness can be effectively improved by introducing weak and brittle bonds into soft and stretchy polymer networks. This toughening method, denoted as the ‘sacrificial bond principle’, has been recently proposed.

Sacrificial Passivation of Nanoscale Metal Powders for Transient Liquid Phase Bonding
MRS Proceedings, 2008ABSTRACTDifferential scanning calorimetry (DSC) was used to evaluate the extent of liquid phase formation in particle compacts (compressed dry powders) comprised of organically capped nano-scale Ag particles and Sn. The Ag nanoparticles employed where synthesized with various organic molecules and procedures to produce particles with a range of capping

Role of Sacrificial Protein–Metal Bond Exchange in Mussel Byssal Thread Self-Healing
Biomacromolecules, 2015Marine mussels tether to seashore surfaces with byssal threads, proteinaceous fibers that effectively dissipate energy from crashing waves. Protein-metal coordination bonds have been proposed to contribute to the characteristic mechanical and self-healing properties of byssal threads; however, very little is understood about how these cross-links ...
