Algorithms for self-healing networks
… This process, where the network can recover itself by maintaining key invariants in response to attack by a powerful adversary is what we call self-healing. Here, we present several fast and provably good distributed algorithms for self-healing in reconfigurable dynamic networks. Each of these …

Mechanochemical Triggers for Self -Healing Polymers
Mechanochemical triggers based on the electrocyclic ring opening of both trans and cis substituted benzocyclobutenes was studied. The products of mechanically-accelerated ring opening were studied by trapping experiments. Ultrasound induces ring opening at 10°C, whereas thermal activation only …

Polymeric capsules for self-healing anticorrosion coatings
… devoted to establishing of a new generation of self-healing anti-corrosion coatings for protection of metals. The concept of self-healing anticorrosion coatings is based on the combination of the passive part, represented by the matrix of conventional coating, and the active part, represented by …

A Self -Healing Poly(dimethyl Siloxane) Elastomer
The self-healing performance of the elastomer is also investigated under torsional fatigue loading. The microcapsule-based self-healing PDMS is capable of recovering a significant portion of the original torsional stiffness and retards dynamic crack growth rate. Depending on the matrix material, a …

Microvascular Networks for Continuous Self -Healing Materials
Microcapsule-based and hollow glass fiber-based self-healing composites enable a single repair of crack damage in a given location. Re-mendable polymers have demonstrated crack mending for multiple cycles, but only with heat treatment and applied pressure. We demonstrate, for the first time, the …

Self-healing laminated composites from prepreg fabrics
… repairing microscale flaws at the initial stage. Self-healing materials have been developed to autonomously detect and repair the damage. One method of self-healing in a material is to incorporate microcapsules which sequester healing agents. These healing agents are autonomously released and wick …

Sustainable bacteria-based self-healing fiber reinforced concrete
Self-healing concrete presents an innovative and eco-friendly solution with the potential to reduce maintenance costs through self-activated crack repair. This study examined the effect of varying bacterial content across different environmental conditions. Additionally, the coupling effect between …

Polydimethylsiloxane-Based Self -Healing Composite and Coating Materials
We demonstrate the bulk self-healing property of a polymer composite composed of a phase-separated PDMS healing agent and a microencapsulated organotin catalyst by chemical and mechanical testing. Another significant research focus is on self-healing polymer coatings which prevent corrosion of a …

Biomimetic vascular self-healing systems for cementitious materials
… resilient structures. A vascular system houses healing agent within its interconnected networks which are incorporated within a cement matrix. It is perhaps the only self-healing approach that has the capability to address different scales of damage in cementitious materials. The main aim of the …

Evaluation of novel autonomous self-healing polymer composite
Autonomous self-healing materials offer a novel ability to self-repair damage caused by fatigue or fracture. Applications in many industries, from medical to aerospace, suffer from formation of microcracks, which often result in catastrophic failure of the product when the cracks remain undetected. …
