Internship | High-throughput screening of bio-based polyesters

Internship | High-throughput screening of bio-based polyesters

About this position

The demand for renewable and bio-based polymer materials is increasing, and in order to address this need, rapid development cycles are required. Bio-based polyester have an incredibly large and diverse design space, which necessitates high-throughput synthesis and characterisation techniques to enable the rapid development of novel materials with targeted properties. At TNO, a novel high-throughput reactor is currently being utilised to support the development of an AI model that enables polymer design via machine learning. This approach allows for rapid, targeted development of bio-based polymer materials.

What will be your role?

In this project, the synthesis of a wide range of bio-based polyesters will be carried out using a high-throughput reactor. The intern will investigate the influence of reactor conditions and feedstock ratios on the final polymer properties. This is critical for ensuring high-quality polymer and for providing reliable training data to the AI model.

During the project, the available bio-based polyester design space will be explored, potentially including complex random co-polymers. Characterization of the synthesised materials will be performed, including NMR, DSC, TGA, and nanoindentation.

Main focus:

• High-throughput synthesis of bio-based polyesters.
• Influence of reactor conditions and feedstock ratio.
• Random co-polymer synthesis.
• Characterisation of synthesised polymers.
• Molecular weight determination via NMR.
• Thermal property characterisation via DSC and TGA.
• Mechanical property characterisation via nanoindentation.

You will work in a passionate team of scientists at TNO, utilising your skills in synthesis and characterisation to contribute to ongoing research. The aim of this internship is to provide students with a taste of research outside academia.

What we expect from you

Candidates should be currently pursuing a degree in Chemistry, Physics, Materials Science, or a closely related field. Knowledge in materials and polymers is crucial. Familiarity with the laboratory work is an advantage. Strong organizational, analytical, and problem-solving skills, as well as an attention to detail, are required.

What you'll get in return

You will, of course, be properly supervised during your work placement and be given the scope for you to get the best out of yourself. Furthermore, we provide:

• A highly professional, innovative internship environment, within a team of top experts.
• A suitable internship allowance (615 euro for wo-, hbo- and mbo-students, for a full-time internship).
• Possibility of eight hours of free leave per internship month (for a full-time internship).
• A free membership of Jong TNO, where you can meet other TNO professionals and join several activities, such as sports activities, (work-related) courses or the yearly ski-trip.
• Use of a laptop.
• An allowance for travel expenses in case you don’t receive an OV-card.
