Cellulose Nanocrystals as Nucleating Agents in Lignin-Based Rigid Polyurethane Foams

This study investigates the incorporation of cellulose nanocrystals (CNC) into rigid polyurethane foams (RPUF) derived from lignin polyol. CNC promoted cellular refinement consistent with a heterogeneous nucleation mechanism, reducing average cell size by up to 18% and improving cellular uniformity, particularly at 0...
