Study of the influence of quick-hardened alloy on the properties of metal polymers

The article explores the effect of quick-hardened alloy PR-N65X25S3R3 based on nickel, (chemical composition – Ni64,6Cr25C1,2Si2,7B2,5Mn0,2Fe3,8) on the physical and mechanical properties of metal-containing polymers. Carried out tests and results have shown that the use of quick-hardened alloys, which are characterized by a set of unique properties, is appropriate. The developed metal-containing polymers that contain aromatic polyamide phenylone and 5 - 20 wt.% of self-fluxing amorphous alloys PR-N65X25S3R3 are characterized by 2 times greater abrasive wear resistance and better adhesive strength between the components. Due to the use of quick-hardened alloy it was possible to increase theeffective filler content from 15 wt.% to 20 wt.% that will increase the electromagnetic properties of metal-containing polymers.

NIR-responsive metal-containing polymer hydrogel for light-controlled microvalve

Metal-containing polymers have drawn considerable interest because of their unexpected and fantastic properties, which can be applied for preparing functional hydrogels. However, covalently cross-linked metal-containing polymer hydrogels have been rarely...

Cyclotriphosphazene-based Derivatives for Antibacterial Applications: An Update on Recent Advances

: As a phosphorus scaffold, hexachlorocyclotriphosphazene (HCCP) is widely used for synthesis of varieties of derivatives, including metal-binding complexes and several unique organometallic compounds, which exhibit potential catalytic, flame retardant and biological activities. Some metal-binding HCCP derivatives have shown antibacterial activities as free ligands and metal complexes. These derivatives can also serve as building blocks for the formation of antibacterial metal- containing polymers. This mini-review is focused on the design and development of HCCP derivatives as potential antibacterial agents with representative examples from recent years, as well as antibacterial mechanisms are also pointed out.
