제목 Preparation and Characterization of Graphene Oxide/Cellulose film and fiber
초록 Graphene Oxide/Cellulose nanocomposite film and fiber were prepared using N-methylmorpholine-N-oxide (NMMO) monohydrate as a dispersing agent for the graphene oxides (GOs) as well as a cellulose solvent. The GOs were dispersed in both NMMO monohydrate and the nanocomposite due to the strong hydrogen bonds of the GOs with NMMO and cellulose. Mechanical properties of the Graphene Oxide/Cellulose film and fiber increased by adding a little amount of GO. The electric conductivities of the composites were recovered from the nearly non-conducting the GO/Cellulose composite by simple heat treatment at 270 ℃. This rrecovery was due to the thermal reduction of the GOs in the nanocomposites.
