Post-doc synthesis and degradation mechanism of fire retardants for polypropylene (project SuFiP-S)

You are a highly motivated researcher with a PhD degree in chemistry, holding skills in organic synthesis and analytical chemistry. You are willing to collaborate closely with both public and private partners on the development of sustainable and fire-safe plastics (polypropylene) based on fully organic phosphorus-sulfur compounds.

Job description
This project is part of the SuFiP-S project where two departments of Maastricht University (Circular Chemical Engineering, CCE and Aachen-Maastricht Institute for Biobased Materials, AMIBM) collaborate with Sabic. The goal of the SuFiP-S project is to develop sustainable and fire-safe plastics (polypropylene) based on fully organic phosphorus-sulfur compounds.

Polypropylene (PP) is a significant plastic in flame retardant (FR) products in electronics and transportation. Single-molecule FRs like phosphorus-sulfur (P-S) FRs are part of the state-of-the-art research for applications in PP due to their promising FR performance at low concentrations. However, P-S FRs are not commercially used because their decomposition mechanisms are unknown during processing and in the use phase, thus leading to poor recyclability. This project proposes a systematic interdisciplinary study on the degradation, processing, and recycling of PP/FR plastics to lay a scientific basis for developing new PP/FR plastics and increasing their recycling quantity and quality.

The task of the post-doc at AMIBM is to synthesize flame retardants and to investigate their degradation mechanism during processing and recycling conditions via analytical techniques. In a first part of the research, the degradation of pure flame retardants will be studied, later the flame retardant blended in a polypropylene matrix will be the focus. The post-doc will work closely together with a PhD student in the group of dr. Ali Gooneie from CCE at UM. The latter are responsible for mechanical recycling studies and modelling work related to the degradation mechanism of the flame retardants. Flame retardants will be upscaled for the testing by the colleagues from CCE. Based on this interaction, the chemical structure of the flame retardant will adapted in order allow better recycling.

The post-doc will be appointed at AMIBM, Maastricht University, which is part of the Faculty of Science and Engineering. You will work in the Sustainable Polymer Synthesis group of Associate Professor Katrien Bernaerts, which focusses on the synthesis and design of polymer materials with tunable properties and recyclability exploiting the functionality of biobased building blocks. You will operate from the Brightlands-Chemelot Campus in Geleen (Nl), where the labs are located.

Research group Sustainable Polymer Synthesis
Main research focus is on the design and synthesis of sustainable polymer materials with tuneable properties for the circular economy. Sustainability entails biobased building blocks (but no biorefinery) instead of fossil raw materials, green routes for polymer synthesis and processing, as well as chemical recycling/reprocessing methods (biodegradability, depolymerization, dynamic bonds) to make the end-of-life of polymers more sustainable. Structure-property relationships of the resulting polymers are evaluated in several fields of application e.g. stimuli-responsive polymers, coatings, fibres, engineering plastics and biomedical materials. Growing focus on the use of artificial intelligence techniques to support and accelerate the experimental work, e.g. data interpretation and prediction of structure-property relationships.
