“…The mechanical properties of these hybrids can be greatly enhanced by using a compatibilizing agent or surface modification modify interaction among all components. Specifically, the addition of MA-PP can efficiently improve the mechanical and thermal properties of PP/cellulose-fibers composites [25][26][27][28]. It is worthy mentioned that the intercalation of small amounts of coupling agent can significantly promote the mechanical performances these composites [29].…”

The uncontrolled recycling activities of waste species can lead to series problems to both environment and human health. In addition, the exploration of environmentally friendly materials has been received growing interests from researchers and academicians. Herein, we investigated the tribological and mechanical properties of wood flour reinforced polypropylene (WF/PP) composites. The WF/PP complexes were successfully fabricated via a controllable injection molding approach using PP frameworks incorporating 5 wt%, 15 wt%, 25 wt%, 35 wt%, 45 wt%, and 55 wt% WF in the presence of maleated polypropylene (MA-PP) as an effective coupling agent to enhance the WF adhesion to the polymeric matrix and promote the interfacial interaction and wettability. Results demonstrate improved mechanical properties and wear resistance of the as-synthesized composites with the increment of WF content, benefiting from the robust interfacial adhesion and collaborative effects of both natural filler and polymeric components. The inherent strength of natural fibers significantly contributes to the overall strength of the resultant composites. Remarkably, the embedment of coupling agent enables superior properties to certain dozens of WF due to further impregnation of filler along the matrix. Thus, our developed synthesis method holds a promise as efficient pathway to fabricate hybrids comprising polymer and natural fibers to achieve a maximum utilization.

“…But one of the winning point of this filler type is its hydrophilicity behaviour. Perhaps, with the type of chemical bonding existed in the graphitic materials, and the synergistic effect after the reinforcement, it may reduce the hydrophobicity of the composite [9][10]. Hence, may reduce the protein adsorption onto its surface.…”

Recent studies have found a rapid increase of ultrahigh molecular weight polyethylene (UHMWPE) wear in the presence of proteins from the synovial fluid. This is due to the high hydrophobicity surface of UHMWPE which allows the proteins to get interacted and adsorbed to the UHMWPE surface. Moreover, since UHMWPE has low thermal conductivity, the heat elevated produced from the articulating contact surfaces would be slowly dissipated and protein structure becoming denatured. The denatured proteins were claimed could increase the adhesive wear response. Thus, the main objective of this study is to evaluate the influence of the graphene oxide (GO) and graphite flake (GF) on the UHMWPE’s heat dissipation and wettability characteristics in regards to reducing the protein denaturation effect on the surface. The surface properties were characterized by using surface energy evaluation, zeta potential, and Fourier Transform Infra-red (FTIR). Following that, wear properties of each UHMWPE composite were evaluated by using a multidirectional pin-on-disc wear test under a lubricated condition. The worn surface of each pin sample was evaluated, and the dominating factors of wear properties were determined. In addition to that, the effect of protein absorption on the UHMWPE composites was also evaluated in this study. The results show both fillers (GO and GF) had no effect in altering the UHMWPE composites’ physicochemical properties. The improvement of UHMWPE composite’s wear properties was discovered to be primarily dominated by the existence of GO filler (1.0 wt%) near the sliding surface has improved the subsurface strength of the material and heat dissipation effect which reduces the denaturation of the proteins.

“…The development of high-performance tribo-materials has become of great interest for the modern bearing industry [22] with a major focus being the development of biotribo-materials in order to achieve energy conservation in combination with a reduced environmental impact [2,12]. Polymer composites have shown the potential to exhibit superior mechanical and tribological performance and thus be utilized as anti-wear and friction materials [13]. However, evaluation of the tribological behavior of polymers and polymer composites is known to be relatively difficult due to their complex multiphase structures [4] and attributed to the fact that friction and wear for polymers are not necessarily proportional to one another.…”

“…However, fatigue wear occurs when the sliding of harder polymers (such as thermosetting plastics) takes place against a smooth surface [9], and the polymer undergoes repeated stressing during rolling and sliding motion [1]. It is notable to mention that, the cutting and ploughing of a harder surface into a weaker surface can be considered as the main mechanism of abrasive wear for polymers and composite materials [13]. In addition, the tribological behavior of polymers and their associated composites can be described mostly in terms of their viscoelastic and temperature related properties.…”

Tribological behavior of unsaturated polyester hybrid composites containing wood flour and carbon nanotubes

et al. 2019

The dry-wear behavior of hybrid composites comprising of multi-walled carbon nanotubes (MWCNTs) and wood flour (oil palm kernel shell powder) within an unsaturated polyester matrix was investigated in this paper. The results revealed that the incorporation of wood flour-even at little as 10 wt% filler content-significantly improved the tribological behavior of the composite. This improvement in tribological behavior was attributed to the transfer of a soft layer of wood flour on the worn area during the wear process, which acted as a self-lubricating material. Investigation of the effect of filler size revealed that composites containing smaller filler sizes exhibited higher values of friction coefficient (µ) and specific wear rate (Ws). This reduction attributed to the creation of a surface with a lower surface roughness (Ra) at the worn area which resulted in a larger number of contacts between counterpart surfaces. In addition, increasing in the normal load resulted in a considerable increment in the values of µ and Ws. Filler treatment with hot alkali solution (1 to 9 wt% concentration) showed that both µ and Ws reached their minimum values at 5 wt% alkali concentration due to improved interfacial bonding between the filler and matrix. Finally, a relatively small amount (0.2 wt%) of well-dispersed MWCNTs within the wood flour polyester composite was found to be capable of improving the tribological behavior of such hybrid composites.
