General background:
Nowadays, thermosetting polymers such as epoxy resins are extensively used as coatings, adhesives, and structural applications because of their outstanding mechanical and electrical properties, chemical resistance, and adhesion. The global thermoset plastic market is about 25 billion dollars. It is very difficult to recycle the thermosets because of the cross-linked nature of the resin. Solvolysis, using reactive solvents to break down chemical bonds in thermoset resins, has been regarded as one of the most promising recycling.

Goal of internship:
Chemical recycling of a typical thermoset epoxy resin via solvolysis.

The Project involves:
1. Solvent selection for solvolysis of epoxy resin based on literature and theoretical analysis.
2. Test the solvents for solvolysis of epoxy resin and optimize the reaction conditions.
3. Characterization of the thermoset and the degradation products using FTIR, HPLC, GC-MS, LC-MS, DSC.
4. Preliminary mechanism analysis of the selected solvolysis methods.

Starting date
September 2022. The length of the assignment is 5 months. The student who will execute the assignment gets a fee of €350,- per month.
The intern will be part of a research team led by the adviser and supervised by Qian Zhou and Dennis Molendijk. The working language can be Dutch and English.

Desirable skills/qualities of the student
The student should be able to carry out independent laboratory research. The preferred background is chemistry.
