Cellulose nanocomposite is one of the most fascinating materials with broad applications. In this work, cellulose-magnetite nanocomposite has been prepared by dispersion of magnetite nanoparticles in a homogenous ionic liquid solution of grafted cellulose. Bagasse cellulose was first grafted with polymethacrylic acid in 1-butyl-3-methylimidazolium, and then fabricated with Fe3O4 nanoparticles during the homogeneous media. The obtained nanocomposite contained high content of iron due to the clelation of the grafted cellulose and Fe3O4 nanoparticles. It also exhibited superparamagnetic behavior with 8.606 emu/g saturation magnetizations. The cellulose-magnetite nanocomposite will be potential for the development of functional cellulose and protective materials for electromagnet radiation or microwaves. |
