Abstract:

The paper presents data on the determination of oil capacity and oligomer capacity of dispersed fillers based on silica with different particle sizes (from 50 nm to 250 microns). It is shown that using the oil absorption and oligomeric capacity data, it is possible to carry out a complete technological classification of dispersed particles by size and use it to create disperse filled polymer composite materials (DFPCM) with a given composition, type and structure parameters, as well as a set of operational properties. The values of the maximum disperse filler content (parameter φm) in DFPCM fo

Abstract:

The mechanical and thermal conductivity properties of two composite elastomers were studied. Styrene–butadiene rubber (SBR) filled with functionalized graphene oxide (GO) and silica nanofibers, and styrene–butadiene–styrene (SBS) block copolymers filled with graphene oxide. For the SBR composites, GO fillers with two different surface functionalities were synthesized (cysteamine and dodecylamine) and dispersed in the SBR using mechanical and liquid mixing techniques. The hydrophilic cysteamine-based GO fillers were dispersed in the SBR by mechanical mixing, whereas the hydrophobic dodecylamine

The paper deals with fundamental regularities of constructing a heterogeneous structure of filler with different types of lattices and structures for creating disperse-filled polymer composite materials (DFPCM) with specified properties. For the first time, the basic principles of designing DFPCM compositions with a given type of heterogeneous structure of dispersed filler (lattice) are presented at the quantitative level. It is shown that the design of all DFPCM compositions should start with the most dense packing of the filler in space, which is determined experimentally for dispersed fille

The influence of the most common stabilizers on the aggregate stability of wollastonite-based microdispersed systems in the aquatic dispersion environment is considered. The optimal parameters, ensuring the production of micro-fillers in the form of stable suspensions, are developed. The application efficiency of the wollastonite-based filler due to its micro-reinforcing properties is revealed. These properties are specified

Abstract:

The challenge of water shutoff in carbonate reservoirs is complicated by the presence of fractures, which cannot be effectively blocked using conventional hydrogel screens designed for granular reservoirs. To reliably seal fractures, fibrous and dispersed fillers are added to hydrogels. These fillers must exhibit affinity for the matrix to ensure the composites can effectively isolate water. Given the wide variability in fracture apertures, it is evident that water shutoff composites should incorporate fibers and dispersed fillers of varying geometric sizes.

Abstract This work analyzed the effects of nano-silicon dioxide (nano-SiO2) fillers on the morphology and mechanical properties of acrylonitrile-butadiene-styrene (ABS)/poly(methyl methacrylate) (PMMA) blends. Nano-SiO2 particles were selectively dispersed in the PMMA phase, and the toughness of the ternary blends was significantly improved when the contents of the nano-SiO2 fillers were below 2 wt%. The stearic acid treatment of nano-SiO2 particles prevented the adhesion between constituents and markedly diminished the toughness of the blends. Nano-SiO2 particles were alternatively treated wi

The effect of the filler loading on mechanical properties, morphology, dielectric strength, and thermal stability of the composites has been analyzed.
