Nanofibers preparation chemical route

Composites of natural cellulosic fibers may have the best option to the array because the nanofibers can interact with other natural materials to form highly ordered structures. The cellulose microlibrils have hydroxyl groups (OH) on their surface, which can form covalent bonds with the matrix. In literature, three alternative routes for the preparation of composites of cellulose are known [40]. The first route refers to the incorporation of hydrophobic libers in matrices such as polyethylene, polypropylene and polystyrene. In this case, it is necessary to a chemical or physical treatment, so that the surfaces of the matrix and the libers... 

Wu et al. prepared composite films from chemically converted graphene and polyaniline nanofibers (PANl-NFs) by vacuum filtration the mixed dispersions of both components [119]. This method provided a new route to graphene-based nanocomposites. The composite film has a layered structure, and PANI-NFs are sandwiched between graphene layers.
