Materials for the biorefinery: high bio-content, shape memory Kraft lignin-derived non-isocyanate polyurethane foams using a non-toxic protocol
James Sternberg, Srikanth Pilla
Abstract
Non-isocyanate polyurethane foams have been synthesized from unmodified Kraft lignin and a renewable diamine creating materials with 100% biobased carbon. The materials demonstrate impressive physical and mechaical properties competing with commercial polyurethanes.
