Cellulose/polydopamine/alumina nanocomposites were formed using ultrasound technique. By the self-polymerization of dopamine, PDA particles were fabricated and homogeneously spread through the chemical interactions in cellulose matrix. The NCs were prepared by insertion of colloidal Al2O3 NPs in a solution of cellulose/PDA complex matrix and after that, the hybrid films with different contents of inorganic phase were obtained by casting method. The nanocomposites surfaces were investigated by using atomic force microscopy (AFM). AFM results showed specific features of nanocomposite surfaces. The enhancement of adhesion properties was qualified by the homogeneous and respectable dispersion of polydopamine-based structures of Al2O3 in the mixed cellulose matrix and these results were accredited to the robust bonding between cellulose and the modified nanostructures.
