| Popis: | The focus of this work is to study the effects of chemical swelling with N,N-dimethylacetamide containing 0.5% lithium chloride and hydrolysis with 64% H2SO4 on the morphology of cellulose nanowhisker (CNW) from oil palm empty fruit bunch microcrystalline cellulose (MCC). FT-IR spectroscopy showed that there are no significant changes in the peak positions, suggesting that the treatments did not affect the chemical structure of the MCC. Atomic force microscopy revealed the rod-like nature of the CNW. X-ray diffraction analysis indicated that chemical swelling improved the crystallinity of MCC while maintaining the cellulose I polymorph. Acid hydrolysis, however, reduced the crystallinity of MCC and displayed coexistence of cellulose I and cellulose II polymorphs. The produced CNW-S and CNW are shown to have an excellent thermal stability and hence have great potential for a range of applications such as reinforcing agents for the manufacture of green biodegradable nanocomposites. |
