- Аннотация: The rheological behavior of new colloid systems based on imide derivatives of cymantrene functionalized with carboxylate groups and their organic analogs was studied for the first time. Rheological fluids were obtained based on nano- and micro-sized particles in polar and non-polar media with different viscosities. The influence of irradiation, temperature and electric field changes in the properties of liquids was studied using macrorheology and microrheology methods. The new rheological fluids are non-Newtonian under the experimental conditions. It has been established that the aggregation of particles in the system was significantly affected by the nature of the medium, in which intermolecular interaction was possible due to the formation of hydrogen bonds and π -stacking. 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, which had a strong effect on the viscosity of the system. The most dramatic change in rheological behavior was observed for cymantrenyl phthalimide with a COOH group (Im1). Moreover, the system based on Im1 exhibited an inverse electrorheological effect due to the electrorotation of particles in the medium. Nanofluids based on manganese nanoparticles suspended in toluene and isopropanol were also obtained, which were fairly stable systems. However, exposure to light led to the destruction of aggregates and a sharp increase in viscosity, after which, under thermal reaction conditions, the systems excited by light did not return to initial state and the change in the viscosity of the liquid remained irreversible.
