Modifying Cellulose Nanomaterials for Wet Compounding into Polylactic Acid
Snapshot: Cellulose nanomaterials (CNMs) have been demonstrated to significantly improve various properties, including mechanical and barrier performance, of polymer composites, but one of the major impediments for producing these cellulose nanocomposites is the profound challenge of drying the nanomaterials without losing the nanoscale structure of the cellulose. In this work, researchers are developing aqueous-based modification and processing strategies to improve the compatibility and processing of CNMs into biobased polymer composites.
