Unraveling the Role of Lignin Oligomers Functionality for the Synthesis of Nonisocyanate Polyurethanes

ChemSusChem, Volume 19, Issue 15, 14 August 2026.
This study reports the synthesis of bio‐based nonisocyanate polyhydroxyurethanes from crude lignins and depolymerized lignin oligomers. The structure–properties relationships were largely explored and highlighted the key role of lignin functionality on the physical properties of the materials. Lignins are the main source of aromatic compounds in nature.

Biobased Polyurethane Films Based on Andiroba (Carapa guianensis) and Buriti (Mauritia flexuosa) Oil Polyols

Journal of Applied Polymer Science, Volume 143, Issue 30, August 10, 2026.
Polyurethane films were prepared from andiroba (Carapa guianensis) and buriti (Mauritia flexuosa) oil‐derived polyols, emphasizing their potential as bio‐based materials. UV–Vis analysis indicates the retention of carotenoid‐related chromophoric features within the polymer matrix.

3D Printing of Bio‐Based Elastomers With High Toughness

Aggregate, Volume 7, Issue 8, August 2026.
This work presents a 3D‐printed bio‐elastomer that simultaneously achieves high mechanical performance (toughness: 156.9 MJ m−3) and high bio‐content (76%), and that is extendable to fabricate tough 3D foams (tensile strength of 1.2 MPa at a density of 0.26 g cm−3). ABSTRACT The rapid development of 3D printing, combined with the urgent need to address

Synthesis of Polyols for Expanded Rigid Polyurethanes by Microwave Liquefaction of Kraft Lignin With Bio‐Based Solvents

Macromolecular Materials and Engineering, Volume 311, Issue 8, August 2026.
This study produced bio‐based polyols from lignin using microwave liquefaction with bio‐derived solvents. The process was optimized by adjusting solvent composition and catalyst type to obtain high yields and a suitable hydroxyl number. Foams made from lignin‐based polyols showed comparable properties to commercial products.
