Reversible Adhesion and Polymer Deconstruction are focus projects of 2019.

Reversible adhesion:

Smart Adhesives

 

In 2019 the reversible adhesion project will get new life. Magnus Hansen-Felby will do his PhD on this topic at under supervision by Kim Daasbjerg, Professor at Department of Chemistry and iNANO, Aarhus University. The project has been a part of Open Science since 2017.

The Science:

In order to assemble unlike materials and allow products to consist of more than one material, a strong adhesive is necessary. However, if you are also interested in reusing the materials after product life-time, you must be able to disassemble the materials again. This should optimally occur upon exposure of the product to specific stimuli. To achieve this, the group working on this project, focus on catechol chemistry. The project will give general insight into the principles of reversible adhesion.

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.

Polymer Deconstruction:

During 2019, polymer deconstruction will be an important theme in Open Science. This project seeks, to chemically break carbon bonds in low value plastic polymer and through this process completely degrade plastic. This will ultimately result in the opportunity to deconstruct or upcycle low value plastic. The primary focus of the project is chemical degradation of PE, PC and PET.

The project is run by Professor Troels Skrydstrup and supported by the Carlsberg Foundation.
