| Abstract | Polylactide (PLA) suffers from deficiencies compared with petroleum-derived materials that limit its immediate adoption as a food packaging material, which may be addressed through compounding with cellulose nanocrystals (CNC). In this work, compatibilized CNC particles are blended with PLA and cast into packaging films to assess their potential for improving food packaging related properties. As a control, the compatibilized CNC particles are also cast in polyethylene (PE). An acetylation reaction and surfactant modification are employed to compatibilize the CNC particles for melt processing with PE and PLA matrices. High quality films are produced with indications of improved mechanical and promising oxygen-barrier results. Further progress will require detailed microstrucrural characterization of the composites to understand the degree of dispersion and thermal degradation, as well as the effect on the host polymer crystallinity. |
