In this work, we investigate the formation of self-healing systems that are able to recover more than once more than one (mechanical or other physical) functionality. To this aim composites were created consisting of a polysulfide thermoset rubber matrix having intrinsic self-healing properties filled with thermally/electrically conductive...

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...

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...

Locally stiffened or ‘stringer’ - skin composite structures are extensively used for lightweight applications in the aerospace industry. Due to localised stiffening, stress concentrations arise which can initiate damage e.g. debonding or delamination, within the composite structure. Critically, this damage can propagate under fatigue loading...

Creation of an ideal self-healing polymer composite material with durable performance could become an alternative to traditional improvement of lightweight constructions. A vascular strategy of the self-healing of the epoxy materials is based on healing agent (HA) delivery to the damage via system of channels formed in the material. The aim of...

Fiber reinforced cementitious composite (FRCC) has a great capability for selfhealing of cracks. Concrete cracks with a sufficiently small crack width (below 0.1 mm) can be closed and self-healed by crystallization of calcium carbonate in the presence of moisture, even in the case of ordinary concrete. Such precipitation is caused by reaction of...

Poly (urea-formaldehyde) (PUF) shelled dicyclopentadiene (DCPD) microcapsules were prepared by in-situ polymerization technology for self-healing concrete applications. It’s found, during the process, sodium dodecyl benzene sulfonate (SDBS) behaves better in emulsification of DCPD than other surfactant of sodium lauryl sulfate (SLS) and styrene...

Plants have inspired the development of numerous novel (self-)adaptive and selfhealing materials, structures and surfaces over the last decade. Examples include: (1) self-repairing elastomers for sealing gaskets and dampers inspired by self-healing processes in latex bearing plants, (2) self-adaptive biomimetic attachment systems inspired by...

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...

The microcapsules of epoxy E-51 resin encapsulated by cured itself were prepared by interfacial curing reaction, in which ethylenediamine (EDA) was employed as curing agent and sulfonated copolymer of styrene and maleic anhydride (SMA) as emulsifying agent. It’s found the morphology of microcapsules strongly depend on reaction time and EDA...

Sol-gel technology is increasingly being used in coatings for corrosion protection and adhesion improvement. So far, the self-healing concept in sol-gel coatings has only been approached from extrinsic healing perspective (i.e. use of nano and micro carriers of corrosion inhibitors) [1]. Despite the benefits of this approach, the damaged area...

Recent developments in self-healing technology inspired by natural biological materials have the potential to dramatically improve the performance and durability of cementitious materials. These self-healing cementitious materials comprise artificial flow networks embedded within the cementitious matrix that upon damage release healing agents...
