This article describes a self-healing coating for corrosion protection of metals, which combines two different types of self-healing mechanisms in one coating with multiple-healing functionality. 2-Mercaptobenzothiazole (MBT) was loaded into layered double hydroxide (LDH) carriers that were mixed into an acrylated polycaprolactone polyurethane-based shape-recovery coating and applied on hot-dip...

Autonomous crack healing in concrete is obtained when encapsulated healing agent is embedded into the material. Cracking damage in concrete elements ruptures the capsules and activates the healing process by healing agent release. Previously, the strength and stiffness recovery as well as the sealing efficiency after autonomous crack repair was well established. However, the mechanisms that tri...

Fully autonomous, room temperature self-healing in PMMA is achieved for the first time through the use of microcapsules containing a solvent. Linear PMMA is embedded with microcapsules (ca. 300 mm) containing a liquid anisole solvent core and a small amount of linear PMMA polymer for healing of crack damage. Specimens containing a range of concentrations of microcapsules were fracture tested an...

Autonomous networks are self-healing, selfmanaging and most importantly independent of human interference. Such networks will be able to be developed in a way that avoids wasting effort on maintaining even simple mechanisms such as storage, scalability and data retention. Systems like these will quickly extend to providing a method of highly scalable platforms that can accommodate real time tra...
