“…Scanning Electron Microscope (SEM) was used on neat UHMWPE, UHMWPE/GO, and UHMWPE/GF at 0.1 and 1.0 wt%, respectively to identify the physical formation of adhesive binding between the particles of matrix and filler. The observation was made after the melt‐blending process of the matrix‐filler mixing powders at 185°C for 60 min 1,10,20,38 . The analysis of the SEM analysis after the melt‐blending stage was practiced by other researchers in their study 20,38 to have an initial prediction on the improved properties of the final composite specimens.…”

“…The XRD was conducted using an X‐ray diffractometer, at room temperature 26°C, operating at 45 kV, and 40 mA over the 2 θ range of 5–50° with a step size of 0.02°. Cu Kα radiation with a wavelength of 0.154 nm was used 1 . The degree of crystallinity of neat UHMWPE and composite UHMWPE with different types of filler and composition were compared and calculated using the below Equation (1) as described by 39…”

“…Ultra‐high molecular weight polyethylene (UHMWPE) has been a prime choice for a prosthetic bearing component since it was introduced in the 1960s. UHMWPE showed good toughness, high impact strength, low coefficient of friction, good biocompatibility, and the highest wear resistance among polymers 1 . There are wide number of joint replacements demanded globally, especially total hip replacement (THR).…”

“…Even though a large amount of literature about the effect of graphite and GO on the mechanical performances of UHMWPE composites have been published, very little investigation has been carried out on their wear properties. In addition, to the best of the author's knowledge, the early work of the UHMWPE composite related to the wear properties was done with unidirectional sliding 1,9,10,22,27,30 as well as multidirectional sliding 35,36 . For example, Reddy et al 22 found in their study that the reinforcement of GF has improved the hardness and wear resistance with increased GF contents from 0.5 to 1.5 wt%.…”

This article aims to investigate the influence of reinforcing graphene oxide (GO) and graphite flakes (GF) fillers into ultrahigh molecular weight polyethylene (UHMWPE) for orthopedic application. These fillers were expected to physically bond to UHMWPE, thus can enhance the subsurface strength, improving the wear behavior of the composites. UHMWPE/GO and UHMWPE/GF composites were prepared at 0.1 and 1.0 wt% by melt‐blending, followed by a compression molding technique. A multidirectional pin‐on‐disc wear test was performed to simulate the kinematic of hip application. Whilst getting exposed in the artificial in‐vivo lubricant bath (30 v/v% diluted bovine serum). Following this, the wear mechanism fostered by each filler (GO and GF) was determined by wear features obtained from the optical microscope and scanning electron microscope (SEM). The crystallinity degree and crystal defect were assessed using x‐ray diffraction (XRD). The mechanical properties of fabricated composites were evaluated by using a universal testing machine and Vickers microhardness. We found that UHMWPE/GO has the lowest specific wear rate due to the improved subsurface strength, as the reduction of a weak adhesive point was observed on the worn surface. Meanwhile, higher GF content (1 wt%) in UHMWPE displayed a lower specific wear rate than neat UHMWPE after completing the 10 km sliding distance attributed to the filler resurfaced, responsible for providing a strong resistance of the shear stress applied upon sliding with the metal counterface. Interestingly, the hardness and tensile strength for both UHMWPE/GO and UHMWPE/GF increased, although the crystallinity percentage was declining compared to neat UHMWPE.

“…Filling modification is a simple and effective way to enhance the wear resistance of UHMWPE plate. The fillers used in wear resistance modification include particles and micro‐fibers that usually show higher hardness than UHMWPE (such as cubic BN, 5 Si 3 N 4 , B 4 C, SiC, 6 AlN 7,8 or carbon fiber 9,10 ) or excellent lubrication (such as graphite, MoS 2, 11 polytetrafluoroethylene, 12 or montmorillonite 13 ). The wear resistance strengthening mechanism of UHMWPE filling modification mainly lies in improving the hardness of UHMWPE or easy constructing a continuous transfer film and decreasing the coefficient of friction in the process of friction 14 …”

A simple and feasible method to enhance the wear resistance of ultra-high molecular weight polyethylene (UHMWPE) fibers was reported. The graphite oxide (GO) prepared using improved Hummer's method was surface modified with hexadecylamine to improve its compatibility with UHMWPE. Combined with well-dispersion of modified-GO (m-GO) in dichloromethane and the fact that the viscosity of UHMWPE suspension can be decreased by dichloromethane, the well dispersed m-GO/dichloromethane was added into UHMWPE suspension to improve m-GO dispersion in UHMWPE fibers. Finally, UHMWPE fibers with different m-GO concentration were prepared using gel spinning technology. The effect of m-GO concentration on the structure and properties of modified UHMWPE fibers were investigated. The results indicated that the melting temperature and crystallinity of m-GO modified UHMWPE fibers increased with increasing of m-GO concentration, while the fiber's crystal sizes and orientation increased, thus the tensile strength of m-GO modified UHMWPE fibers remained almost undamaged. The introduction of m-GO is beneficial to the formation of smooth transfer film on fiber's surface, which enhanced the self-lubrication of UHMWPE fibers. Compared with pure UHMWPE fiber, the UHMWPE fiber containing 1.5 wt% m-GO had enhanced wear resistance by 55.4% and still maintained high tensile strength of 29.98 cN dtex −1 .
