“…However, a decrease in the particle size reduces the value of φ m , which can decrease for nanoparticles to 0.05. This is due to the formation of strong but loose clusters that do not collapse even at very high compression pressures of nanoparticles [23]. Therefore, it is impossible to introduce a significant amount of solid filler consisting of nanoparticles into the matrix.…”

The current state of the rheology of various polymeric and other materials containing a high concentration of spherical solid filler is considered. The physics of the critical points on the concentration scale are discussed in detail. These points determine the features of the rheological behavior of the highly filled materials corresponding to transitions from a liquid to a yielding medium, elastic–plastic state, and finally to an elastic solid-like state of suspensions. Theoretical and experimental data are summarized, showing the limits of the most dense packing of solid particles, which is of key importance for applications and obtaining high-quality products. The results of model and fine structural studies of physical phenomena that occur when approaching the point of filling the volume, including the occurrence of instabilities, are considered. The occurrence of heterogeneity in the form of individual clusters is also described. These heterogeneous objects begin to move as a whole that leads to the appearance of discontinuities in the suspension volume or wall slip. Understanding these phenomena is a key for particle technology and multiphase processing.

Currently, to obtain light polymer composite materials with high strength characteristics, hollow microspheres of various nature (glass, quartz, polymer, etc.) are used as fillers. Hollow glass microspheres of different grades (manufactured by JSC «SIO Stekloplastik») were studied by various methods, the disperse structure was described using the generalized parameters model, the light dispersion-filled polymer composite materials (DFPCM) were classified according to the structural principle, generalized and reduced parameters were calculated, and the structure, compositions of light CMs on polymer matrices of various nature were designed.
