| Outline of Final Research Achievements |
A simple and efficient method for the preparation of cellulose nanofibrils (CNFs)/polymer nanocomposite materials was developed, using polystyrene and poly(methyl methacrylate) as polymer matrices. CNFs were prepared by TEMPO (2,2,6,6-tetramethylpiperidine-1-oxyl)-mediated oxidation of wood cellulose. In the polymer nanocomposite materials, the CNFs were individually and homogeneously dispersed, and therefore, the nanocomposites showed good optical transparency, which is as high as original polymers. The nanocomposites exhibited improved strength, Young’s modulus, and thermal dimensional stability with increasing CNF content. Therefore, this preparation technique provides a simple environmentally-friendly method for the preparation of novel CNF/polymer nanocomposite materials.
