【Abstract】 Viscosity is one of the major indicators of rheological properties. In this paper, we summarize recent developments in research on coal tar pitch rheological properties for carbon materials, with focus on relations between apparent viscosity and the properties such as temperature,shear rate,molecule composition,molecular weight distribution and additive. It is also pointed out that the properties are influenced by many factors, and play an important role in carbon materials process and properties.更多还原
