Recently, cellulose nanocrystals have attracted considerable attention as 'green' nano-size reinforcement materials with unique mechanical properties and a high aspect ratio. A homogeneous dispersion of the nanocrystals is necessary in the polymer matrix in order to achieve the ideal improvement as a filler material. However, the large hydroxyl groups on the nanocrystal surface interrupt the dispersion in the hydrophobic matrices. In this work, bacterial cellulose nanocrystals (BCNCs) were successfully modified using lauroyl acid chloride and poly(ethylene glycol) methyl ether in order to improve their adhesion to the hydrophobic polymer matrices. The modification was confirmed using FT-IR and the element analysis. X-ray diffraction confirmed that crystalline structure of the nanocrystals did not change during the modification. |
