Effect of Hemicellulose Hydrolysate Addition on the Structural Change and Redispersion Characteristic of Cellulose Nanofibrils |
| 초록 |
Nanocellulose is getting attention as an alternative material of petroleum-based polymers due to its high mechanical and thermal properties. From this standpoint, it is necessary to scale up in production, storage, and transportation for the utilization of nanocellulose in various industrial fields. However, cellulose nanofibrils (CNF) lose their nano properties due to agglomeration between nanofibrils in drying. For this reason, commercialized CNF is mainly supplied in aqueous-dispersed suspensions. In this study, xylose, a hemicellulose hydrolysate, was used as an additive to prevent interfibrillar hydrogen bonds of CNF during the dehydration. Oven dried CNF/xylose films were prepared and morphology and transparency were analyzed. The optimal content of xylose was determined through redispersion kinetics and stability tests. The washing process easily removed xylose. Lastly, physicochemical recovery of the redispersed CNF was evaluated through particle size and rheological analysis. |
