“…The creation of a composition of iron oxides and polymer also solves the problem of particle aggregation due to the fact that iron ions are well distributed along the polymer chain, dispersed over the entire surface [16]. In addition, a polymer with additives of iron oxide NPs usually has hydrophilic surface properties, which helps to prevent the adhesion of microorganisms to the surface [17,18].…”

New Organosilicon Composite Based on Borosiloxane and Zinc Oxide Nanoparticles Inhibits Bacterial Growth, but Does Not Have a Toxic Effect on the Development of Animal Eukaryotic Cells

The present study a comprehensive analysis of the antibacterial properties of a composite material based on borosiloxane and zinc oxide nanoparticles (ZnO NPs). The effect of the polymer matrix and ZnO NPs on the generation of reactive oxygen species, hydroxyl radicals, and long-lived oxidized forms of biomolecules has been studied. All variants of the composites significantly inhibited the division of E. coli bacteria and caused them to detach from the substrate. It was revealed that the surfaces of a composite material based on borosiloxane and ZnO NPs do not inhibit the growth and division of mammalians cells. It is shown in the work that the positive effect of the incorporation of ZnO NPs into borosiloxane can reach 100% or more, provided that the viscoelastic properties of borosiloxane with nanoparticles are retained.

In studies of ballistic impact, the materials used in body armor must have high hardness, light weight, fatigue resistance, corrosion resistance, and other high performance characteristics. Aramid fibers are widely used in anti-ballistic materials. To facilitate the further development of aramid materials, this study reviews aramid research in recent years and analyzes the main factors affecting, and new methods for optimizing, anti-ballistic performance, with the emphasis on bulletproof fabrics. This review provides suggestions for future research and use of aramid materials for anti-ballistic performance.

“…Due to unique self-healing and shear-stiffening properties, PBS was found to be particularly useful in impact protective equipment, such as D3O TM foam, which is one of the most known applications of PBS in the market (it is PU foam with PBS as an additional protective compound). [16] PBS is also found in other foam-based composites, [17,18] Kevlar-based composites, [19,20] and double network composites. [2][3][4] Despite the wide range of various PBS composites for impact protection, the potential of PBS itself has hardly been studied.…”

It is possible to tailor the dynamic response of polyborosiloxanes (PBS) based on picking the right molecular weight of a precursor. The molecular weight of hydroxy-terminated polydimethylsiloxane (PDMS) defines the shear-stiffening performance of PBS due to straightforward condensation reaction between hydroxy end groups of PDMS and boric acid. Introduced borono groups behave as stickers, hence, are prone to supramolecular interactions. New correlations are discovered for five PBS synthesized from hydroxy-terminated PDMS with different molecular weights. Si─O─B infrared band intensities for all PBS follow the same trend with molecular weight as the number of PDMS hydroxy groups which confirms the full completion of the reaction. After synthesis, the molecular weight of PBSs remained almost the same, which indicates the absence of significant chain scissoring, polymerization, or crosslinking. During the rheological analysis, it is found that crossover point modulus follows the same trend as the number of PDMS hydroxy groups and Si─O─B band intensities. PBS demonstrates a linear increase in peak forces with molecular weight during the drop weight impact test. The low molecular weight of a precursor, hence, a high number of stickers is a primary requirement for effective protection against low-velocity impact.
