There is increasing global demand for carbon fibers, with 10% annual rate up to 89,000 tons in 20101. The rising interest to replace petroleum-based precursors (such as polyacrylonitrile and mesoporous pitch)2 with renewable and sustainable alternatives has motivated our efforts for developing bio-based alternatives. Therefore, we applied lignocellulose for developing carbon fibers from wet-spun natural fibers. The high content of lignin in the precursor was counted as an advantage to achieve carbon fibers with high yield. Lignocellulose-derived carbon fibers (LCCF) showed much higher mechanical properties, conductivity and carbon yield compared to the nanocellulose-derived carbon fibers. The LCCF provided potential applications for supercapacitance. Figure 1 illustrates the LED light circuit successfully built with 1 cm long of LCCF.
