Eindhoven University of Technology

Job description

Eindhoven University of Technology is an internationally top-ranking university in the Netherlands that combines scientific curiosity with a hands-on attitude. Our spirit of collaboration translates into an open culture and a top-five position in collaborating with advanced industries. Fundamental knowledge enables us to design solutions for the highly complex problems of today and tomorrow.The Department of Mechanical Engineering department conducts world-class research aligned with the technological interests of the high-tech industry in the Netherlands, with a focus on the Brainport region. Our goal is to produce engineers who are both scientifically educated and application-driven by providing a balanced education and research program that combines fundamental and application aspects. We equip our graduates with practical and theoretical expertise, preparing them optimally for future challenges.IntroductionAre you eager to work on the next step in polymer recycling which goes beyond shredding and mixing?
And are you driven to make an impact on the sustainability of plastic materials?
Then this PhD position is an excellent fit for you!Job DescriptionAbout the ResearchAt TU/e, materials research is a cornerstone of our academic mission, with polymers and soft matter recognized as a major theme. Within the Department of Mechanical Engineering, the Processing and Performance (P&P) research group aims to revolutionize the design of polymer products and shaping processes. We are transitioning from traditional trial-and-error approaches to virtual prototyping powered by quantitative predictive models.The P&P group bridges the gap between molecular design, processing techniques, and end-product properties. Our research spans the entire spectrum of polymer rheology, processing, and mechanical performance, targeting both the fluid (processing) and solid (properties) states. This integrated approach combines sophisticated experimental techniques, rheological modeling, and reliable predictive modeling to tackle real-world challenges.About the ProjectDespite significant efforts to recycle plastic waste efficiently, traditional recycling methods face critical limitations. These methods often involve costly, energy-intensive processes that fail to meet stringent purification requirements for sensitive applications like food packaging and medical products.In this PhD project, you will develop a novel recycling approach leveraging the sensitivity of polyolefin crystallization and melting behaviors to typical processing conditions such as extrusion and injection molding. By exploiting these unique characteristics, you will aim to achieve precise separation and spatial fractionation of polymer mixtures based on polyolefin type and molecular weight. This innovative methodology has the potential to overcome the limitations of conventional recycling, offering sustainable solutions for high-purity applications.

• Identify the processing conditions, i.e., flow fields and temperature profiles, that seem most effective in molecular phase separation at the nanoscale.
• Develop an experimental toolkit to inform and validate these predictive models.
• Compare the de-mixing efficiency for different material compositions and molecular weights.

The results of your project will facilitate the efficient removal of undesirable components in mixed waste-streams, thereby significantly enhancing the performance and quality of polyolefin recyclates. Importantly, this innovative technique needs to be designed for seamless integration into existing compounding lines, offering a practical and scalable solution to overcome current recycling inefficiencies while advancing sustainability in high-value applications.Job RequirementsWe are looking for a candidate with intrinsic motivation and enthusiasm, holding a MSc. degree in Mechanical Engineering (or equivalent) and having a strong background in polymer processing / polymer mechanics.
The following experience, skills and interested are preferred:

• A master’s degree (or an equivalent university degree)Affinity with both experimental and numerical work.
• Experienced in characterization of complex fluids / rheology (preferably polymers and/or other viscoelastic materials).
• Driven to improve sustainability of polymer materials.
• Excellent communication skills.
• Ability to take ownership of the research project.
• Interested in collaborating with academic and industrial partners.
• Motivated to develop your teaching skills and coach students.
• Fluent in spoken and written English (C1 level).
