Characterization And Properties Of Carboxymethyl Celluloses – Oil Palm Empty Fruit Bunch Hemicelluloses Blend And Nanocomposite Films

In this study, hemicelluloses were successfully extracted from oil palm empty fruit bunch. Hemicelluloses produced through alkali-ethanol extraction technique. The hemicelluloses then blended with carboxymethyl cellulose (CMC) at various hemicelluloses loading (20, 40, 60, and 80 wt %) by using solu...
