“…As a result, the adhesive qualities of the surface were shown to increase even more. It is feasible to develop oxygen-rich nanofilms on PEEK with a high surface energy, which can result in an increased cell performance [24,25].…”

There has been a recent uptake in the use of polyether-ether-ketone (PEEK), which is an organic thermoplastic polymer, in the manufacturing of various medical devices, implants, and equipment. Finding the best time and procedure for PEEK after sulfonation is the goal of this research. A total of 30 PEEK discs were sulfonated in this study by immersing them in concentrated (H2SO4) sulfuric acid for various durations and subsequently treated using various post-treatment techniques. Five experiments were carried out, aimed studying the effect of immersion time (5 s–2 min). The methods used as post-treatment were hydrothermal treatment, immersion in NaOH, and washing with acetone. The sulfonation time was measured, and the post-treatment techniques, surface characterizations, were conducted using scanning electron microscopy (SEM) (Electron Optics Instruments, LLC., West Orange, NJ, USA), atomic force microscopy (AFM) (AFM, Vía Burton, CA, USA), and hydrophilic properties. The results were confirmed by attenuated total reflectance-Fourier transform infrared spectroscopy (ATR-FTIR). The findings of this study demonstrate that sulfonating PEEK caused a structure with a porous network to form in every sample. As the sulfonation time increased, the porous structure became more noticeable and the concentration increased. As a consequence, the roughness of the surface increased notably, and the modified PEEK surface’s wettability improved noticeably. Hydrothermal treatment was determined to be the most successful way for eliminating the leftover sulfuric acid, and sulfonation for 2 min was determined to be ideal. By understanding the best post-treatment procedures and ideal sulfonation duration, a theoretical foundation for the production of sulfonated PEEK for orthopedic uses may be laid.

“…1 Here, modifying the ETT surface through coatings can be an interesting approach that might present a solution to these problems. [2][3][4][5] Indeed, coatings generated from different materials have already been used to modify the surfaces of many devices such as medical equipment and improved important properties including the tribological performance, 3,[6][7][8] anti-biofouling behavior, 9,10 biocompatibility, 11 and hemocompatibility. 12 In recent work, we introduced a setup that enabled us to perform ex vivo extubation tests on porcine tracheas, and we employed this setup to assess the functionality of mucin coatings generated on endotracheal tubes (ETTs).…”

“…Ye et al found that thinner CFRPs exhibit increased susceptibility to damage during relative sliding, whereas thicker CFRPs have higher resistance to ploughing, which impacts the friction and wear characteristics [7]. Solid lubrication coatings that can withstand high-temperature, high-pressure, and high-vacuum conditions, can enhance the hardness and wear resistance of the base material, thereby extending the lifespan of CFRP and reducing frictional losses in CFRP components [8,9].…”

Solid lubricating coatings were applied onto Carbon Fibre Reinforced Polymer (CFRP) substrates, using epoxy resin as the adhesive agent, graphite (C) and molybdenum disulphide (MoS2) as lubricating components, and alumina (Al 2 O 3 ) as the functional filler. The test parts were prepared by spraying technology and co-curing process. The mechanical properties of the coating were evaluated using Bar hardness and wear rate tests, while the microstructure of the coating was analysed using EDS elemental analysis technology. The test results revealed that the filler content had a significant impact on the mechanical properties. The performance of the coating was determined by the formation of a lubricating film, which resulted from the accumulation of lubricant and reinforcing material during external friction. Scheme T7 yielded the best coating performance with a ratio of epoxy resin to molybdenum disulphide to graphite to alumina of 20:8:3:2.
