Abstract

A multi-walled carbon nanotube (MWCNT)/cellulose composite was synthesized to improve the mechanical strength of regenerated cellulose film. N,N-carbonyldiimidazole was mixed with functionalized MWCNTs and sonicated at 60°C for 12h. The resulting MWCNT-imidazolidewas mixedwith cellulose solution, and reacted at various temperatures for various times. The occurrence of covalent bonds between MWCNTs and cellulose was investigated using Fourier transform infrared spectroscopy and Raman spectroscopy. According to mechanical tensile tests, Young's modulus of the MWCNT/cellulose composite was found to be 11.2 GPa, an increase of approximately 110% with respect to regenerated cellulose film.
