Rheological behaviors of Graphitic oxide/Sodium alginate dispersions

摘要

One kind of the carbonaceous materials with high performance was chosen to prepare dispersions of GO/SA. The influence of GO contents on rheological properties of SA solution was studied with rotational rheometer under different test conditions. Steady rheological results showed that the solutions exhibited shear-thinning behaviors. The viscosities decreased with the increasing of shear rates. Dynamic rheological results showed that both SA solutions and SA/GO suspensions exhibited liquid-like behaviors. Moreover indicate that incorporation of small amounts GO can significantly increase the G' and G'' of SA spinning solution, reflecting good dispersion of GO nanolayers in SA solution, which was proved by Cole-Cole curves.
