Self-healing in cementitious materials : materials, methods and service conditions Universiteit Gent
Supramolecular thermoplastics and thermoplastic elastomer materials with self-healing ability based on oligomeric charged triblock copolymers Vrije Universiteit Brussel Universiteit Gent Universiteit Antwerpen
Supramolecular polymeric materials constitute a unique class of materials held together by non-covalent interactions. These dynamic supramolecular interactions can provide unique properties such as a strong decrease in viscosity upon relatively mild heating, as well as self-healing ability. In this study we demonstrate the unique mechanical properties of phase-separated electrostatic supramolecular materials based on mixing of low molar mass, ...
Macro- and micro-modeling of crack propagation in encapsulation-based self-healing materials : application of XFEM and cohesive surface techniques Universiteit Gent
Stress concentrations and bonding strength in encapsulation-based self-healing materials Universiteit Gent
Experimental characterization of the self-healing capacity of cement based materials : an overview Universiteit Gent
This paper, prepared in the framework of the COST Action SARCOS WG2 activities (http://www.cost.eu/COST_Actions/ca/CA15202), provides an overview of the main concepts underlying the experimental characterization of the self-sealing capacity of cement-based materials. This effort intends to pave the way towards standardization of such experimental methods for a comparative assessment of the self-healing capacity of different cement-based ...
Development of optimized autonomous self-healing systems for epoxy materials based on maleimide chemistry Universiteit Gent
Self-healing materials are coming of age Universiteit Gent
While natural materials such as bone or skin are able to heal themselves in an autonomous manner after mechanical damage, traditional man-made materials generally lack this intrinsic capacity for self-healing. In 1969, self-healing properties were for the first time built-in inside polymeric materials[1] and in the following decades publications about self-healing in thermoplastic and cross-linked systems and concrete appeared.[2] Although, it ...
Evaluation of self-healing in cementitious materials with superabsorbent polymers through ultrasonic mapping Vrije Universiteit Brussel
The maintenance and repair of concrete infrastructure covers an increasing portion of the annual construction budget. For this reason, self-healing cementitious materials have been investigated thoroughly in literature. One way to achieve an effective self-healing composite is by promoting their inherent repair ability through the inclusion of superabsorbent polymers (SAPs). Thanks to their large absorption capacity upon contact with water, ...
Visualization of self-healing materials by X-ray computed micro-tomography at UGCT Universiteit Gent
This work presents recent advancements in X-ray micro-computed tomography (XRMCT) of self-healing materials at Ghent UniversityU+2019s Centre for X-ray Tomography (UGCT). Results of XRMCT imaging in a self-healing polymer system are shown to demonstrate the use of XRMCT in self-healing studies. Furthermore, two new XRMCT scanners are presented. The HECTOR scanner was designed for large samples and strongly attenuating samples, and is therefore ...
