Abstract

The paper presents results of investigations on the effect of the addition of graphene oxide (GO) on the structural properties of composite cellulose fibers (CEL). GO/CEL fibers were obtained from a solution of CEL in ionic liquid – 1-ethyl-3-methylimidazole acetate – with the addition of GO dispersion in DMF. A classic wet spinning method was used using water and methanol as coagulants. Results have shown that the addition of GO increases the crystallinity of fibers to 31–40.8%. Moreover, these results indicate a significant impact of the coagulant used in the fiber forming process. Methanol coagulated fibers have greater porosity and larger pore sizes than water coagulated fibers.
