Autonomic self-healing thermosetting polymers or elastomers have been substantially studied, in which polymerization of the healing agents released from pre-embedded capsules serves as the key issue. As for thermoplastics, another major class of polymeric materials, however, researches on their self-healing approaches are less reported. Here in...

Bituminous materials form a class of materials that possess the intrinsic ability to selfheal. This self-healing capability is evidenced by the observation that the service life of these materials ‘in the field’ exceeds the service life as predicted by standard mechanical laboratory tests. This mismatch between laboratory prediction and field...

An international cooperation research project has been financially supported by China Nature Science Foundation, which consists of three relatively independent, but strategically integrated research sub-programs, aiming at the formation of a selfhealing system based on the microcapsule principle for the cementitious composites. In this paper, a...

Bacteria induced calcite precipitation has been proven to be effective in making concrete structure self-healing. In Microlab TU Delft, the concept has been enhanced by developing a liquid bacteria-based concrete repair system. The solution contains calcite precipitating bacteria, nutrients and buffer compound which may demonstrate high...

The thermally reversible Diels-Alder adducts are attractive building blocks for the design of intrinsic self-healing materials that do not have an additional healing agent but possess the capability to repair the damage through inherent reversibility of bonding into the polymer matrix. We report the development of new thermally responsive...

Supramolecular polymers gained a great success in the last years as self-healing materials and many different systems have been developed. These polymers combine the advantages of intrinsic and autonomic self-healing systems. In 2010, Montarnal et al. developed a class of epoxy-based hybrid networks that combine both chemical and supramolecular...

Crack is called the intrinsic flaw of concrete that is inevitable for concrete infrastructures during their service life. The presence of crack offer aggressive agent access to pass through, which has a direct impact on durability, therefore resulting in shortened service life. Nevertheless, the influence of crack on the durability can be...

While conventional self healing materials focus on the restoration of mechanical properties, newer generations of self healing materials focus on the restoration of other functional (i.e. non-mechanical) properties. Thermal conductivity is an example of an important functional property of a Thermal Interface Material (TIM) for LED’s and...

This paper presents a vision of a sustainable and resilient built environment that is comprised of materials and structures that continually monitor, regulate, adapt and repair themselves without the need for external intervention. In this way, these self?healing materials and intelligent structures will significantly enhance durability and...

Platinum nanoparticles, which are used as catalysts in Proton Exchange Membrane Fuel Cells (PEMFC), tend to degrade after long-term operation. We discriminate the following mechanisms of the degradation: poisoning, migration and coalescence, dissolution, and electrochemical Ostwald ripening. There are two ways to tackle this problem. The first...

Polyborosiloxanes (PBSs) are viscoelastic, transparent, colourless, self-healable polymer matrices, synthesized by reacting linear polydimethylsiloxanes (PDMSs) with boric acid (BA) above 150°C. BA takes part not only in cleaving the PDMS chains, but also contributes boronic-acid like moieties to the cleaved chain ends, which provide...

The subject of this paper is the mathematical modelling of the crack self-healing process. For self-healing modeling of cracked structures the bridged crack approach is used. In the frames of this approach is assumed: 1) there is a crack in a structure after service loading; 2) there are bonds between surfaces of a crack (which are induced by a...

One of the most broadly reported self-healing schemes is that pioneered by White and Sottos et al. in which a polymer matrix is co-embedded with a catalyst and microcapsules containing a reactive healing agent. Although this field has been steadily growing over the past 10 years, little discussion of extension into biomaterials has taken place...

Self-assembled systems formed of micelles or vesicles have frequently been discussed as model systems for self-healing materials because their structure is dictated by thermodynamics and hence they quickly restore upon perturbation. In this aspect, they mimic many natural systems such as biological cells. However, in contrast to most synthetic...
