Atomic Force Microscopy Investigation of Surface of Alumina Nanocomposite

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#
