Self-healing polymers

Self-healing polymers are smart stimuli-responsive materials eabling to restore properties to avoid damage. As an example, self-healing polymers should undergo mechanical healing in response to an applied stimulus. Such healable polymers and composite materials offer the ability to prolong the functional lifetime of their resulting structures and coatings.

ICON2 PUrePair: Polyurethane foams and elastomers with autonomic repair.

ICON2 PUrePair: Polyurethane foams and elastomers with autonomic repair.

To eliminate the negative effects of the ageing of plastics, a self-healing approach can be used that is triggered by a degradation mechanism, like e.g. cracking. In this way, a repair function is integrated within the material itself and eliminates the need for human intervention and/or repair. This should ultimately lead to several advantages: - A longer lifetime of the product itself - The ...

Towards dynamic preventive self-restoring of thin films based on photo-reversible covalent networks

The objective of this project is the synthesis, characterization, and optimization of novel thin cross-linked polymer films with multiple reversible covalent bonds. Such films could find application as a sustainable self-restoring alternative for regular surface coatings prone to fatigue- and micro damage, thus reducing the use of raw materials and the emission of harmful components into the ...

Self-healing Actuators for Robotic Applications

Self-healing Actuators for Robotic Applications

The doctoral project is a multidisciplinary research on the implementation of available self-healing (SH) materials in compliant actuators, speci c for robotic applications. The project will be conducted on the University of Brussels (VUB) at the research group Robotics and Multibody Mechanics (R&MM) and with a strong involvement of the Physical Chemistry and Polymer Science (FYSC) research ...

SECEMIN: SElf-healing CEmentitous and MINeral building materials.

SECEMIN: SElf-healing CEmentitous and MINeral building materials.

Aim of the current SBO-project (SIM SHE program on Engineered Self-Healing Materials) is to develop new routes and to further elaborate on concepts for autonomous self-healing of cementitious and mineral building materials. Important objectives are: - regain impermeability of the material and as such safeguard the durability of the structure ("sealing") - restore mechanical properties of the ...

Novel Active Protection Systems On Metals (NAPROM)

Novel Active Protection Systems On Metals (NAPROM)

This SBO-project NAPROM is part of the SIBO network SHE and is focusing on the development of novel active protection coatings for metal surfaces, based on self-healing polymers combined with corrosion inhibitors.

Self-healing polymer networks based on thermoreversible covalent bonding

Self-healing polymer networks based on thermoreversible covalent bonding

A new class of polymeric materials has been developped by introducing reversible covalent bonds into covalently cross-linked polymer network systems, resulting in reversible covalent polymer network systems (RCPNS). In this project the reversible covalent bonds are thermally reversible bonds, e.g. by means of the Diels-Alder reaction between furan and maleimide function groups. Polymer ...
