The Microstructure and Rheology of Carbon Nanotube Suspensions
| Carbon nanotubes (CNTs) are nano-scale structures consisting of rolled graphite sheets. Because of their high mechanical strength, low density and high thermal and electrical conductivity, CNTs are being extensively researched as fillers in numerous matrices.
The initial challenge is finding a suitable method for dispersing the powdered CNTs in the suspending medium. The microstructure of the final dispersion will affect the macroscopic properties of the product. Suspension rheology also affects the processability of the material. It follows that understanding the microstructure and rheology of CNT suspensions is important for both material processing and product design. This project includes:
