Preparation of cellulose nanocomposites
A. Dufresne, Federal university of Rio de Janeiro, Brazil
The preparation of elongated rod-like nanoparticles from lignocellulosic fibers and their use as a reinforcing phase in a polymeric matrix is discussed. The hierarchical structure of natural fibers is described and the expected effects of changing the scale of cellulosic particles from micro to nano are outlined. The preparation methods and morphological features of the ensuing nanofibers are also discussed. The different ways of processing nanocomposite films using a polymer matrix are presented. The main properties of these films, in terms of microstructure, thermal properties, mechanical performances, swelling behavior and ...
