Reversible Adhesives

Student: Asger Agergaard and Søren Lykke Pedersen

An Open Science project on reversible adhesives has been running during spring 2017, providing interesting results worth building upon (Findings of the prior project is found here).

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. The project will involve design, synthesis and tests of candidate adhesives for both model and industrially relevant substrates.

Methods

Chemical synthesis and screening of adhesive behavior e.g. through shear mechanical testing. Additionally, investigations of structures of adhesives by various spectroscopies and/or rheology. This has so far been done using electrochemistry – but it would be interesting to be able to do it in non-conductive systems.

 

Industrial Applications

Several application areas could potentially be included and the scope expanded to include biopolymers, metals, plastics, etc.

 

Involved partnes: Aarhus University (Henrik Birkedal, Kim Daasbjerg), ECCO, VELUX, RadiSurf
