Tailored organic polymers and composites towards a circular society

Our group designs, produces and tests new organic polymers for a greener and more circular society. We are primarily interested in porous polymers in the form of so-called organic framework compounds and porous organic polymers (POPs) and how these can be combined with other (organic) materials into composites. Porous materials are interesting because they enable a variety of applications and in our research, we focus on energy storage and electrocatalysis as well as adsorption and capture of metal ions from aqueous solutions. By combining organic synthesis, material characterization and electrochemistry, we develop structure-property relationships to establish which structures and material properties perform best in various applications. The research takes place in collaboration with other researchers in Sweden and abroad as well as with industrial partners in Sweden and in the Baltic region.
