Creation of New Rheological Fluids Based on Cyclopentadienyl Manganese Tricarbonyl Containing Imide Cycle and Study of Their Properties

The rheological behavior of new colloidal systems based on imide derivatives of cymantrene and their organic analogs has been studied for the first time. Rheological fluids based on nano- and microsized particles in polar and non-polar media with different viscosities have been obtained. The influence of irradiation, temperature, and electric field changes on the mechanical properties of fluids has been studied using macrorheology and microrheology methods. Irradiation or heating of systems led to both the destruction of intermolecular bonds and the formation of large aggregates depending on the nature of the solvent. The system based on cymantrenyl phthalimide with a COOH group exhibited an inverse electrorheological effect due to the electrorotation of particles in the medium. Nanofluids based on manganese nanoparticles suspended in toluene and isopropanol have also been obtained. However, exposure to light led to the destruction of aggregates and a sharp increase in viscosity.
