Viscosity of Polyacrylonitrile Solutions Containing Carbon Nanoparticles

This article is devoted to the assessment of the impact of carbon nanotubes (CNT) and carbon black particles on the viscosity of polyacrylonitrile (PAN) solutions. The dependences of the dynamic viscosity of dilute solutions on the content of carbon nanoparticles and temperature is investigated. It is shown that the addition of CNT to PAN solutions in dimethylformamide can lead to an abnormal reduction in their dynamic viscosity.
