Study on Fabrication of Graphene Oxide (GO) /Carboxymethyl Cellulose (CMC) composite fiber by using wet-spinning

Graphene Oxide (GO) has been announced as a highly anticipated material because solution process is applicable, utilizing its high solubility in various solvents, which is important for the industrial application. However, as compared with other materials such as CNT fiber and Carbon fiber, the mechanical property of GO LC fiber is relatively low. Since the nature of high aspect ratio of GO sheets as well as various oxide groups in GO sheets inevitably induces voids in GO fiber, it leads to low mechanical properties of GO fiber. Accordingly, there have been many efforts to fill these voids with other materials so as to increase the mechanical property of GO fiber. In this study, as the abundant hydroxyl groups of CMC are capable of hydrogen bonding with GO, CMC was used as a filler for GO/CMC composite fiber. As a result, the fabricated GO/CMC composite fiber showed reinforced mechanical property higher than that of pristine GO fiber.
