Abstract

The effect of two types of carbon nanoparticles, i.e., shungite carbon (SC) and multiwalled carbon nanotubes (MWCNTs), on the mesomorphic and rheological properties of cholesteric mesogen in the concentration range of 0.005–0.04 wt % has been reported. The main physical parameters for tribological applications, such as phase transition temperature, viscosity, elastic modulus G', loss modulus G'', and complex viscosity η*, have been studied. The preference of using SC as a lubricating coolant additive component has been shown in the comparison with MWCNTs.
