Existing materials are challenged by mechanical and chemical forces that limit their function and lifetime. For these reasons there is an urgent need for materials
that can heal themselves and/or efficiently be recycled as clearly evidenced by the recent focus on circular economy, both globally and in Denmark. For example, many classes of self-healing materials have been proposed, differing by whether they allow one time or repeated healing, whether they are slow or fast acting, and whether they are self-initiating or require an external trigger to work. Many excellent selfhealing materials have been proposed, however, it remains a very significant challenge to incorporate such properties into multifunctional materials, because these chemistries may interfere with the other desired function or vice versa.

Reversible assembly/dis-assembly of polymer-metal parts

Simple 2D model of catechol-based reversible adhesive system

Current Project:

Reversible Adhesives

A general understanding of the underlying principles of reversibility of the adhesion between two non-specific materials is now sought investigated. The adhesive should preferably rely on catechol moieties possibly combined with trivalent metal ions for reversibility. To prove the principles of reversibility a demonstrator will be created as a general assessment of such properties.

Reversible Adhesives Based on Catechols and Metal Ions

 Strong adhesion between different substrates is of highest importance in many different industries and is used both in protection of material-surfaces and in joining different materials together. Often materials are joined by physical joining, but it is also possible to do chemical joining of different materials.
