【 摘 要 】
In order to develop functional natural fiber reinforcements derived from cellulose nanofibers (CNF), surface modification of CNF by oxidative polymerization of dopamine was carried out. Resulting polydopamine (PDA)-coated CNF was blended with polypropylene (PP) to prepare the surface-modified CNF/PP nanocomposites. Obtained PDA-coated CNF and its nanocomposites were analyzed as to their morphologies, structures, and various properties. From analyses by Fourier transform infrared spectroscopy, scanning electron microscopy equipped with energy dispersive spectroscopy, X-ray photoelectron spectroscopy, and thermogravimetry, it was clarified that the treated CNF surface was homogeneously coated by PDA without re-aggregation of CNF. Moreover, it was confirmed that the PDA-coated CNF/PP nanocomposites had excellent mechanical performances and good antistatic properties.
