Cellulose has been studied a lot for its eco-friendly, biocompatible and biodegradable properties. Cellulose does not melt well in common solvents because of hydrogen bonds. Carboxymethyl cellulose is, however, water soluble and is easy to process. Montmorillonite (MMT) is a clay reinforcing material widely used in polymer-clay composites. Polyhedral oligomeric silsesquioxane (POSS) has good thermal, mechanical properties and can widen the distance between layers of sodium MMT. Previously, we investigated on the bionanocomposite films using three materials : microcrystalline cellulose, MMT, and POSS with ammonium moieties (ammonium-POSS). POSS with imidazolium moieties (imidazolium-POSS) as filler may improve the thermal stability of the composite films because of imidazolium moieties with high thermal stability. Therefore, in this work, we prepared carboxymethyl cellulose/MMT bionanocomposites and studied on their properties.
