Aalto University’s School of Chemical Engineering, Department of Bioproducts and Biosystems, invites applications for

Postdoctoral Researcher in the Field of Lyocell Fiber Spinning


IONCELL-F™ is a new sustainable process for the production of man-made cellulosic fibers (MMCFs) based on cellulose pulp dissolution in an ionic liquid (IL), air gap spinning of the solution (spinning dope) in a water (H2O) bath and a subsequent solvent recovery step in which the water is removed from the IL. The whole process is operated in a closed loop [1]. Over the past six years, the process has been developed step by step on a laboratory scale. In addition to the fine tuning of process parameters, mainly in the fiberline, the focus is now increasingly on the development of process-product relationships for a variety of raw materials. A more precise and reliable development of stable spinning conditions is also the subject of further investigations. This work requires knowledge and experience in the physical chemistry of biopolymers and a good basis in polymer analytics.

The position is situated within the Department of Bioproducts and Biosystems on the main campus of Aalto University in Otaniemi.

Your role and tasks

  • Learning and performance of airgap spinning according to the Ioncell™ process
  • Development of relevant process property relationships within the Ioncell™ process
  • Analysis and physicochemistry of ionic liquids, fiber modification and fiber characterization
  • Publishing the results in a peer-reviewed journal (optional)


The eligible candidate should have a solid background in polymer chemistry, physics or polymer engineering with experience in biopolymers, preferably cellulose and the corresponding.

The candidate should also have:

  • PhD in polymer chemistry, polymer physics or (polymer) engineering
  • High motivation for research
  • Good written and oral communication skills in English
  • Experience in carrying out independent research and working in a team environment

Salary and contract terms

The salary is based on Aalto University’s salary system. The contract includes occupational health benefits and Finland has a comprehensive social security system.
