Polymer Technology

Professor Jukka Seppälä leads the Research Group of Polymer Technology that focuses on teaching and research related to synthesis and characterization of novel polymers.
Tensile testing polymer samples

Main focus areas include synthesis and characterization of polymers and development of new materials utilizing polymerization techniques and composite technology. This requires a sound knowledge of chemistry, chemical engineering and material science. Particular fields of interest are polymerization reaction engineering and chemical modification of polymers.

Current research topics include e.g.: novel biomaterials for 3D fabrication of biomedical applications as well as novel sustainable and super-strong biopolymers. High-quality of the research is assured by a professional and efficient staff as well as first-class comprehensive research equipment.

Research projects in Polymer Technology are funded by Academy of Finland and Business Finland. Some projects include co-operation with companies to develop novel industrial polymers with cutting-edge competitive properties. International and national co-operation is active in many projects.

Cra-Max-S, Business Finland, 2017-2020

Patient specific composite scaffolds for treatment of large craniomaxillofacial defects. 

The aim of the Cra-Max-S project is to create new personalized treatments for healthcare and improve treatment results in large bone defects in the cranio-maxillofacial area by developing a functional workflow for producing custom made implants.

The Cra-Max-S project is research collaboration project combining in depth knowledge from:

  • Research Group of Polymer Technology at Aalto University
  • Advanced Production Technologies research group at Aalto University
  • Department of Oral and Maxillofacial Diseases, University of Helsinki and Helsinki University Hospital
  • Department of Biomaterials Science and Technology, University of Twente (The Netherlands).

Design Driven Value Chains in the World of Cellulose (DWoC), Tekes, 2013-2018


A multi-disciplinary research collaboration project funded by Tekes, focused on finding new and innovative applications for cellulosic materials. The DWoC project combines design thinking and design-driven prototyping with a strong competence in technology development. The goal is to make Finland the source of value-added cellulosic products and business concepts and to accelerate the transformation of the current large-scale forest industry into a dynamic ecosystem for the bioeconomy containing both large and small-scale businesses. Major application areas include textiles, fashion, interior decoration, health products, architecture and construction.
