Nanotechnology : emerging applications of cellulose-based green magnetic nanocomposites

Abstract

In recent years, a new type of nanocomposite – cellulose based hybrid nanocomposites, which adopts cellulose nanofibers as matrices, has been intensively developed. Among these materials, hybrid nanocomposites consisting of cellulosic fibers and magnetic nanoparticles have recently attracted much attention due to their potential novel applications in biomedicine, textronics, security papermaking and packaging. The incorporation of the magnetic nanoparticles, e.g. Fe₃O₄ magnetites, which possess controllable collective magnetic properties, enables new functionalities that are impossible with each component alone. In contrast to other studies, recent work aims to develop nanocomposites where both matrices and particles are in true nanoscale such that higher mechanical, physical and chemical properties imparted from nanocelluloses can be retained while offering magnetic capabilities as mentioned above. Here, we will briefly describe the synthesis processes of cellulose nanofibers and magnetic nanoparticles as well as recent developments and potential applications.
