dc.descriptionNanocomposites of cellulose acetate and sodium montmorillonite were prepared using the solution intercalation method with different solvents. The effects of solvent type on the morphology, thermal and mechanical properties of the nanocomposites were investigated by X-ray microtomography and diffraction, field emission scanning electron microscopy, analytical transmission electron microscopy based on electron loss spectroscopy imaging and dynamical mechanical analysis. XRD and TEM results indicated that the dispersion and delamination of the clay are achieved when the solvent presents favorable interactions with the clay. In this case, the storage modulus and the glass transition temperature are significantly higher than those of pure cellulose acetate. The results show that the solvent has a major effect in controlling the morphology of cellulose acetate and cellulose acetate nanocomposite and could be used as a process parameter to produce films with a range of properties.
