Conclusion
In this paper, the regenerated cellulose films were successfully prepared using different cellulose (pine, cotton, bamboo, MCC)as raw materials and ionic liquid 1-ethyl-3-methylimidazoliumacetate (EmimAc) as solvent. The FT-IR spectra and XRD showed the transition from cellulose I to II had occurred after the dissolution and regeneration process. Morphology analysis, by SEM and AFM, indicates that the cellulose film prepared by cotton cellulose displayed a more homogeneous and smoother morphology as compared with other samples, which served as good evidence for complete dissolution of cotton linters in ionic liquids. Furthermore,the thermal analysis showed that cotton cellulose film sample presented the highest thermal stability. In addition, the cellulose films prepared by pine cellulose displayed a better film formation and significant high tensile strength. In this study, cellulose films possessed notable properties were prepared from pine and cotton linter cellulose materials, which open a way for the utilization of these materials in further industrial application.
