“…Figure a shows the chemical structures of pristine and D-ZnO-UHMWPE fibers. The pristine UHMWPE fibers have four absorption peaks at 2917, 2849, 1473, and 717 cm –1 , which could be contributed to −CH 2 antisymmetric stretching vibration, −CH 2 symmetric stretching vibration, −CH 2 deformation vibration, and −CH 2 in-plane swing vibration, respectively. , Compared with the pristine UHMWPE fibers, the D-ZnO-UHMWPE fibers present two new absorption peaks due to the coating of a PDA layer between UHMWPE fibers and D-ZnO. A new broad absorption peak in the range of 3000–3673 cm –1 is due to the stretching vibrations of the −OH and −NH groups .…”

“…These surface-treating techniques have positive effects on improving adhesion of UHMWPE fibers; however, they may change the crystallinity of fiber surfaces, causing the reduction of mechanical performances . To avoid the above problem, Fang et al decorated UHMWPE fiber surfaces with PDA layers and ZnO nanoparticles to enhance interfacial adhesion of UHMWPE fibers/rubber composites, and the mechanical testing showed that the interfacial adhesion property was improved greatly with no decrease in the base fiber strength.…”

Fiber-reinforced composites with excellent mechanical performances usually have a good interface property between fibers and the matrix to achieve effective load transfer. In this paper, structure decorations on the ultrahigh molecular-weight polyethylene (UHMWPE) fiber surface were explored to enhance the interface properties between fibers and the rigid polyurethane (RPU) matrix. Donut-shaped zinc oxide (D-ZnO) crystals grew on the fiber surface, and the morphologic and structural changes were characterized. The possible growth mechanisms of D-ZnO were discussed. The mechanical performances of UHMWPE fibers and corresponding composites were tested. The tensile strength of D-ZnO-UHMWPE fibers/RPU exhibited a remarkably 127.9% increase relative to pure RPU, and the impact toughness was increased by 155.2%. The investigations demonstrated that the decoration of D-ZnO could enhance the mechanical performances of the composites effectively. Moreover, further analysis indicated that adding D-ZnO-UHMWPE fibers to the RPU matrix provided more crack expansion paths, which improved the toughness of the composites.

“…Most recently, UHMWPE was incorporated with 0.1 wt% boron carbide by twin screw extrusion method at 200 °C to improve its physical and mechanical performance [ 25 ]. The improved wear resistance of UHMWPE was discovered to be due to increased entanglement in amorphous and increased content of the interphase (better shear resistance), as well as the load-bearing effect of the particles [ 134 ].…”

Functional Ultra-High Molecular Weight Polyethylene Composites for Ligament Reconstructions and Their Targeted Applications in the Restoration of the Anterior Cruciate Ligament

The selection of biomaterials as biomedical implants is a significant challenge. Ultra-high molecular weight polyethylene (UHMWPE) and composites of such kind have been extensively used in medical implants, notably in the bearings of the hip, knee, and other joint prostheses, owing to its biocompatibility and high wear resistance. For the Anterior Cruciate Ligament (ACL) graft, synthetic UHMWPE is an ideal candidate due to its biocompatibility and extremely high tensile strength. However, significant problems are observed in UHMWPE based implants, such as wear debris and oxidative degradation. To resolve the issue of wear and to enhance the life of UHMWPE as an implant, in recent years, this field has witnessed numerous innovative methodologies such as biofunctionalization or high temperature melting of UHMWPE to enhance its toughness and strength. The surface functionalization/modification/treatment of UHMWPE is very challenging as it requires optimizing many variables, such as surface tension and wettability, active functional groups on the surface, irradiation, and protein immobilization to successfully improve the mechanical properties of UHMWPE and reduce or eliminate the wear or osteolysis of the UHMWPE implant. Despite these difficulties, several surface roughening, functionalization, and irradiation processing technologies have been developed and applied in the recent past. The basic research and direct industrial applications of such material improvement technology are very significant, as evidenced by the significant number of published papers and patents. However, the available literature on research methodology and techniques related to material property enhancement and protection from wear of UHMWPE is disseminated, and there is a lack of a comprehensive source for the research community to access information on the subject matter. Here we provide an overview of recent developments and core challenges in the surface modification/functionalization/irradiation of UHMWPE and apply these findings to the case study of UHMWPE for ACL repair.

In the contemporary modern mining sector, rubber conveyor belts are extensively and frequently utilized. Exceptional tear resistance and high elongation of the top cover rubber of the belt are imperative. In this investigation, a portion of natural rubber (NR) underwent partial vulcanization in advance. Subsequently, this pre‐vulcanized NR (PNR) was mixed with the NR matrix via mechanical blending. Due to the increased viscosity resulting from pre‐vulcanization, the PNR may disperse in the NR matrix, maintaining a specific microstructure without complete dissolution. During subsequent vulcanization, the PNR could co‐vulcanize with the NR matrix, forming a well‐bonded interface and ultimately yielding self‐reinforced NR (SNR) composites. The influences of the mass ratio of PNR to the NR matrix, sulfur content in PNR and pre‐vulcanization time on the mechanical properties of the SNR composites were thoroughly investigated. The results indicated that adding PNR effectively improved the tear strength of NR. When the PNR replaced 20 wt% of NR, sulfur content in PNR was 2.4 phr and pre‐vulcanization time was 2 min, the tear strength, stress at 300% elongation and wear resistance of SNR composites increased by 34.1%, 16.6%, and 10.2% compared to NR control sample, while elongation at break remained at 898%. These findings suggest that it is possible to enhance the tear strength of rubber without compromising elongation at break.
