“…Ultra-high molecular weight polyethylene (UHMWPE) is a type of engineering thermoplastic that has been widely used as a self-lubricating polymer in friction units due to its superior tribological properties such as low coefficient of friction, wear resistance, high impact toughness, corrosion resistance, water absorption, and biocompatibility [1,2]. However, UHMWPE also has disadvantages such as low surface hardness, poor abrasion resistance and flexural strength, and poor creep resistance [3,4]. Therefore, to introduce UHMWPE more broadly into engineering and its application in the harsh conditions of modern industry, it is necessary to modify its mechanical and tribological properties.…”

In this study, the tribological properties of nanocomposites based on ultra-high molecular weight polyethylene (UHMWPE) filled with nano-CuO and 2-mercaptobenzothiazole (CuO/MBT) in mass ratios of 1:1 and 2:1 were investigated. In the supramolecular structure of UHMWPE nanocomposites, spherulites of several hundred micrometers in size are formed. The density of UHMWPE nanocomposites slightly increases relative to the pure polymer, reaching a maximum at 2 wt.% CuO/MBT in both ratios. The Shore D hardness and compressive stress of the UHMWPE nanocomposites showed an improvement of 5–6% and 23–35%, respectively. The wear resistance and coefficient of friction of UHMWPE nanocomposites were tested using a pin-on-disk configuration under dry friction conditions on #45 steel and on P320 sandpaper. It was shown that the wear rate of UHMWPE nanocomposites filled with 2 wt.% CuO/MBT decreased by ~3.2 times compared to the pure polymer, and the coefficient of friction remained at the level of the polymer matrix. Abrasive wear showed an improvement in UHMWPE nanocomposites filled with 1 wt.% CuO/MBT compared to the polymer matrix and other samples. The worn surfaces of the polymer composites after dry friction were examined by scanning electron microscopy and IR spectroscopy. The formation of secondary structures in the form of tribofilms that protect the material from wear was demonstrated. Due to this, the wear mechanism of UHMWPE nanocomposites is transformed from adhesive to fatigue wear. The developed materials, due to improved mechanical and tribological properties, can be used as parts in friction units of machines and equipment.

“…They proved that the optimal conditions for achieving the highest pull-out strength were 9 wt.% PEW-g-PMMA, 12 wt.% silane coupling agent, and 100 °C coating temperature. The authors concluded that the modification approach with PEW-g-PMMA alone or in combination with a silane coupling agent was effective in improving the interfacial adhesion performance of UHMWPE fiber without damaging its intrinsic properties [ 152 ].…”

Hot-melt adhesives (HMAs) are thermoplastic materials that can bond various substrates by solidifying rapidly upon cooling from the molten state, and their modification with organosilicon compounds can result in crosslinking behavior, characteristic of gels. Organosilicon compounds are hybrid molecules that have both inorganic and organic components and can enhance the properties and performance of HMAs. The gel aspect of HMA with and without organosilicon modifiers can be considered in organosilicon-modified systems, the modifiers are often either sol–gel condensation products or their mechanism of action on the adherent surface can be considered of sol–gel type. The purpose of this manuscript is to present the current state of the art on the formulation, characterization, and application of HMAs and optimize their performance with organosilicon compounds for application in various industries such as automotive, construction, and photovoltaics. This review covers articles published within the period of 2018–2022. The article is divided into sections, in which information about hot-melt adhesives is described at the beginning. The following part of the presented review focuses on the composition of hot-melt adhesives, which takes into account the use of organosilicon compounds. The last part of this review outlines the future trends in hot-melt adhesives.

Ultrahigh molecular weight polyethylene (UHMWPE) fiber is a high-performance material with superior properties of high strength and modulus, low density, wear resistance and corrosion resistance. But the development of UHMWPE fiber reinforced polymers is hindered due to its inert inactive surface and poor interfacial adhesion with polymer matrix. This work presents the research progress on surface modification techniques, including ‘dry’ treatment, strong oxidant treatment, chemical grafting and coating, of UHMWPE fiber and the mechanisms of the improvement on surface properties and interfacial adhesion strength between the UHMWPE fiber and the polymer matrix. Application status of UHMWPE fiber such as aerospace, ocean engineering and individual protection is introduced.
