In this study, novel polyurethane/cellulose hybrid bionanocomposite films have successfully been
prepared by dispersing microcrystalline cellulose in a polyurethane matrix. Incorporation of microcrystalline
cellulose in a polyurethane matrix improved the mechanical properties significantly. The
polyurethane/cellulose bionanocomposites were characterized by Fourier transform infrared spectroscopy,
X-ray diffraction and transmission electron microscopy (TEM). The TEM results confirm that
the nanoparticles were dispersed uniformly in polymer matrix. Additionally, thermogravimetric analysis
data showed an improvement of thermal stability of novel nanocomposite films as compared to the neat
polymer.
