From our collaboration with the Laboratory of Polymeric and Composite Materials, Center of Innovation and Research in Materials and Polymers (CIRMAP) of the University of Mons, a recent publication has appeared in ACS Sustainable Chemistry & Engineering. The paper demonstrates that non-isocyanate polyurethanes (NIPUs) with ferroelectric properties can be successfully synthesized using a solvent-free reactive extrusion process.
