The development of polylactide (PLA)/cellulose nanocrystals (CNC) nanocomposites in the aim to increase gas barrier properties has been widely studied, but gave rise conflicting results. To better understand underlying transport mechanisms, PLA/CNC were produced at concentrations between 5 and 50 wt%. role interface for permeability was investigated using three different CNC surface grafts, nam...

The isolation of nanocellulose has been extensively investigated due to the growing demand for sustainable green materials. Cellulose nanocrystals (CNCs) and cellulose nanofibers (CNFs), which have same chemical composition but different morphology, particle size, crystallinity, other properties depending on precursor synthesis method used. In comparison, CNC particles a short rod-like shape sm...

We study composites of cellulose nanocrystals (CNCs) in an ionomer matrix poly(ethylene-stat-sodium acrylate) and find that direct cellulose/cellulose interactions the composite are not a requirement for achieving reinforcement. While isotropic only show slightly enhanced stiffness compared to neat ionomer, more substantial increase Young’s modulus by factor up 5 is achieved uniaxial alignment ...

The anticoagulant activity of surfaces decorated with cellulose nanocrystals (CNCs) prepared via sulfuric acid hydrolysis, is explored. Such surfaces bear a high amount of negatively charged sulfate groups, which mimic the naturally occurring anticoagulant heparin in terms of charge density. It is demonstrated that CNC decorated surfaces significantly enhance the coagulation times of blood plas...
