“…The tensile properties of BC/UHMWPE composites are compared with some other particulate‐reinforced UHMWPE composites in previous literatures, such as hydroxyapatite , Al 2 O 3 , quartz , and Ti particles . The filler loading and reinforcing effect are both higher in our current work compared to these literatures.…”

Highly filled bamboo charcoal (BC)/ultra‐high molecular weight polyethylene (UHMWPE) composites were prepared using extrusion and hot‐compression molding methods. The addition of BC remarkably improved the tensile properties of UHMWPE composites. When the BC content reached 70 wt%, the tensile strength and Young's modulus rose from 28.0 and 326.6 MPa for the neat UHMWPE to 128.9 and 2,027.7 MPa, increasing by 360 and 520%, respectively. The incorporation of BC also significantly improved the creep resistance, especially at high temperature. The creep strains of the composites with 60, 70 and 80 wt% were reduced by 70.1, 78.3, and 85.2% compared to the neat UHMWPE at 80°C, respectively. To understand the mechanism, the Burger's model was employed to illustrate the influence of BC on the creep performance of the polymer composites. The addition of BC also increased the electrical conductivity of the composites: the composite with 80 wt% BC had a conductivity of 0.53 S/cm. Moreover, the thermal stability of BC/UHMWPE composites improved apparently with the increased charcoal loading. POLYM. COMPOS., 39:E1858–E1866, 2018. © 2018 Society of Plastics Engineers

“…A 3D porous pennisetum purpureum (PP)/polylactic acid (PLA) based scaffold was produced and characterized with good properties for construction of implantable tissue-engineered cartilage [6]. Senatov et al [7] developed a material based on ultra-high molecular weight polyethylene (UHMWPE). They increased the wear-resistance in three dierent samples, and found that they can be suitable for cartilage replacement as well.…”

Localized cartilage damage is a common problem for younger patients. This can heal, but often results in a painful condition that requires intervention. A welded-woven three-dimensional polymer fabric has been suggested as a suitable cartilage replacement because such materials closely match the mechanical properties of cartilage. However, such materials fare poorly when evaluated with respect to wear. A microscopic investigation of wear mechanisms showed that it is critical that the bers not deect laterally under a normal load. This observation led to the use of a new process for selective laser welding of the surface layers of three-dimensional fabrics in order to improve their wear resistance. Experimental evaluations were made in a pin-on-disc arrangement with a biomimetic loading. All materials used in the studies have previously been used in orthopaedic devices or meet the requirements for United States Pharmacopeial Convention (USP) Class VI biocompatibility approval. The wear rates were signicantly reduced and the lifespan of the fabrics was markedly improved due to surface welding, making this a viable option for cartilage replacement in vivo.

“…Fan and his colleagues [47] utilized the interaction between the partially engaged molecular chains of UHMWPE and the medium crystal phases of PP to realize external stress-free two-way SME of the specimens. Senatov et al [48] have researched UHMWPE/Al 2 O 3 nanocomposites as a material for damaged cartilage replacement.…”

Modified ultra-high-molecular-weight polyethylene (UHMWPE) with calcium stearate (CS) and polyethylene wax (PEW) is a feasible method to improve the fluidity of materials because of the tense entanglement network formed by the extremely long molecular chains of UHMWPE, and a modified UHMWPE sheet was fabricated by compression molding technology. A Fourier-transform infrared spectroscopy test found that a new chemical bond was generated at 1097 cm−1 in the materials. Besides, further tests on the thermal, thermomechanical, mechanical, and shape memory properties of the samples were also conducted, which indicates that all properties are affected by the dimension and distribution of crystal regions. Moreover, the experimental results indicate that the addition of PEW and CS can effectively improve the mechanical properties. Additionally, the best comprehensive performance of the samples was obtained at the PEW content of 5 wt % and the CS content of 1 wt %. In addition, the effect of temperature on the shape memory properties of the samples was investigated, and the results indicate that the shape fixity ratio (Rf) and the shape recovery ratio (Rr) can reach 100% at 115 °C and 79% at 100 °C, respectively, which can contribute to the development of UHMWPE-based shape memory polymers.
