Regenerated cellulose fibers from rice straws with a diameter of 10 to 25 m
um and initial modulus of 11 to 13 GPa were prepared by wet spinning in ric
e straw/N-methylmorpholine- N-oxide (MMO) solution. X-ray diffraction analy
sis indicates that the rice straw regenerated fibers are classified as cell
ulose (II). From the regenerated cellulose fiber based on rice straw, mesop
orous carbon fiber was prepared by carbonization. This observation indicate
s that a potential utility of rice straw as a new mesoporous materials.
