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.

“…(Tao et al, 2021) In a research work, high-density polyethylene (HDPE) was added to UHMWPE polymer by changing its density, and a comparative X-ray phase analysis of the obtained sample showed that (110) and ( 200) lines (peaks) of UHMWPE polymer lattice, it is said that this improves the mechanical and strength properties. In (Feng, et al, 2021) X-ray phase analysis of Cu oxides obtained by electrodeless deposition on the surface of UHMWPE polymer showed that lines (110) and ( 200) (peaks) of UHMWPE polymer appear, and copper oxide CuO (11-3) and Cu 2 O (111), ( 200) showed the appearance of lines. X-ray phase analysis of coatings obtained after thermal spraying with the addition of 10 to 40% SiO 2 powder to polymer powder, based on literature reviews, is shown in Fig.…”

The polymer coating layer was obtained by adding SiO 2 powder and diabase to the composition of ultra-high molecular weight polyethylene and spraying it with a gas flame. The effect of mineral additives on the chemical composition and phase transition of the obtained coatings was explained by the methods of X-ray phase and infrared spectral analysis. X-ray phase analysis showed that the polymer consists of an orthorhombic network, peaks (110) and ( 200), characteristic of the polymer, appear, the intensity of the line (110) of the phase in the initial pure state of the polymer coating reached 14000; decreased to 2500, with an increase in the amount of continuous SiO 2 to 40%, it can be seen that the intensity of the polymer lines decreased to 2000, on the contrary, the intensity of the lines of the hexagonal lattice (101) SiO 2 increased from 500 to influence on the intensity of polymer lines. In general, analyzing the lines of the diffraction pattern, it can be seen that the polymer melts up to 200 0 C, and given the fact that SiO 2 , as an individual mineral substance, melts at a very high temperature, it was proved by analyzing the literature and experiments confirming the absence of phase exchange between the polymer and the mineral powder consisting of SiO 2 . It has been established that spraying with the addition of 10-40% silicon oxide to the polymer composition, the absence of mutual phase exchange between the polymer and the mixture added to it does not significantly affect the crystalline structure of the coating and the degree of crystallization, the degree of crystallization is (64 ± 3)%. The results of the study of the infrared spectrum showed that the chemical structure of the polymer coating with the addition of SiO 2 in an amount of 10-40% does not change, compared to the original polymer (UHMWPE). This showed that the SiO 2 did not adversely affect the chemical structure of the polymer and that the polymer did not degrade, when it sprayed with a gas flame.

“…CuO can be easily synthesized and its nanoparticles have more superior properties in terms of wear resistance and reduction in the coefficient of friction than other nanoparticles such as aluminum, zirconium, iron, and cobalt oxide [19,20]. However, the literature review showed that there are not many papers where nanoscale copper oxide is used as a modifier in the development of UHMWPE-based composites [21][22][23][24][25].

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.
