▎ 摘　　要

To improve the interfacial properties of Alfa cellulosic fibers (AF) and graphene nanoplatelets (GNPs), AF were subjected to an alkali treatment. The hydrogen bonding interactions between the treated natural fibers and the GNPs facilitate the dispersion of the latter on the surface of the fibers to give biomaterials (AF/GNPs). The structural, physical, and morphological properties of the prepared biomaterials were investigated using various techniques such as Fourier-transform infrared (FTIR) and RAMAN spectroscopies, thermogravimetric analysis (TGA), and scanning electron microscopy (SEM). Morphological analysis revealed that the applied surface treatment of AF was efficient what allowed a good distribution of the GNPs sheets on the fiber interfaces. The combination of AF and graphene nanoplatelets (GNPs) opens new ways to produce new biomaterials with fascinating physicochemical characteristics and performance. (c) 2021 Elsevier B.V.
