“…Therefore, a useful strategy would be to replace normal saline with a liquid that can assist with wound repair and promote muscle growth. Water-based lubricants exhibiting good biocompatibility with the human body and a high lubrication effect have already been developed by some researchers ( Qin et al, 2018 ; Lu et al, 2021 ). These are composed mainly of deionized water and lubricant additives, such as nanoparticles ( Chen et al, 2021 ; Perumalsamy et al, 2021 ; Rahman et al, 2021 ; Sun et al, 2021 ; Tang et al, 2022 ), polymers ( Liu et al, 2021 ; Perumalsamy et al, 2021 ; Wang et al, 2021 ; Zheng et al, 2021 ), and ionic liquids ( Tang et al, 2018 ; Wang et al, 2018 ; Tang et al, 2019 ; Amann et al, 2020 ; Dong et al, 2020 ).…”

The proportion of pregnant women giving birth through cesarean section is increasing annually worldwide. However, post-cesarean section scar diverticulum is a common condition that occurs and requires better surgical strategies than the methods currently used. We hypothesized that using biological lubricant topically on the incision area during C-section could be an option to minimize the scar. This water-based polyethylene glycol (PEG)/chitosan (CS) composite lubricant was prepared via ultrasonic blending. The product was characterized using scanning electron microscopy, X-ray photoelectron spectroscopy, X-ray diffraction, Fourier-transform infrared spectroscopy, and Raman spectroscopy. The thermal stability of the materials and their heat absorption and release during heating were analyzed using thermogravimetric analysis and differential scanning calorimetry. Tribological tests proved that the PEG/CS composite had a better lubrication effect than either the PEG or CS lubricant alone, and the cell viability experiments verified that it had good biocompatibility. Finally, application of the composite lubricant onto the backs of mice modeling full-thickness skin incisions further confirmed that the product improved both the re-epithelialization and the collagen levels of the wounded skin. In conclusion, we expect our newly formulated PEG/CS composite lubricant to be useful not only for managing post-cesarean section scar diverticulum but also for healing skin wounds in general.

“…There are small and uniform marks on the ball. The difference between the hardness of the PE ball and Al disk is significant, and the microconvexity of the hard surface will be embedded in the soft surface when the two surfaces are touching so that the surface of the ball has a lot of wear (Lu et al , 2021). After adding KL, its wear is shown in Figure 5(b)–(f).…”

“…This is mainly because of the special properties of the ball and the disk. With the increase of load, the softer PE balls are seriously worn out and a large amount of wear debris appears, thus assuming an auxiliary lubrication effect (Lu et al , 2021; Guermazi et al , 2008). It can be concluded from Figure 6(b) that when the load is 4 N, the average COF is 0.089.…”

Purpose Kelp is widely productive and inexpensive. The purpose of this study is to explore kelp liquid (KL) as an environment-friendly water-based lubricant, which is expected to replace some industrial lubricants and protect the environment while satisfying lubricating performance. Design/methodology/approach In this experiment, the soaked kelp was broken up by a wall-breaking machine to get the KL by a centrifuge. Elements and crystal structure of KL samples were characterized by X-ray photoelectron spectroscopy, X-ray diffraction and Raman spectra. The friction test is carried out by the relative movement of the polyethylene ball and the aluminum disk on the friction tester. Findings Friction experiments showed that 0.1 Wt.% KL has a good lubrication effect, and the average coefficient of friction is 0.063 under the condition of applying a 10 N load and moving at a speed of 2.0 cm/s. KL has good thermal conductivity with excellent cooling effect and high intermolecular force which makes high viscosity for excellent lubricating behavior, at the meantime molecules in solution remain stable which shows an excellent dispersibility. Originality/value At present, the research on kelp mainly focuses on its medicinal value and abundant nutritional value, and the research on its lubrication effect is less. Based on this situation, this paper explored the characteristics of KL as an environmentally friendly lubricant, which is expected to be used as a green cutting fluid.

“…Secondly, due to the low hardness of the high density polyethylene (HDPE) balls, wear occurs during the friction process, which may make the dropped material transfer to the surface of the disc to form a transfer film. [58] The greater the load, the faster the transfer film was formed and the better the lubrication effect will be. This also explained the phenomenon that the coefficient of friction decreases as the load increases under a pure water system.…”

In this work, Palygorskite (Pal) nanorods, chitosan (CS), and polyethylene glycol (PEG) are used to prepare new composite lubricants in order to improve the lubrication performance of water. The tribological experimental results showed that the composite lubricant composed with 1 wt% Pal, 10 wt% PEG and 2 wt% CS has excellent lubrication performance. The tribological data showed that the friction coefficient reached 0.021, and the composite lubricant lubrication performance was about 4 times higher than that of deionized water. The materials were characterized by scanning electron microscope (SEM), thermogravimetric analyses (TGA), differential scanning calorimetry (DSC), Fourier transform infrared (FT-IR), X-ray diffraction (XRD), and X-ray photoelectron spectroscopy (XPS), which revealed that the composite lubricant contained many oxygen-containing functional groups, and there was no chemical reaction between these functional groups. Instead, a lubricating film that can reduce friction and wear was formed through the hydrogen bond effect between functional groups. In this paper, a general and simple preparation method of new composite lubricant was proposed, which can be wildly used in many fields such as water-based lubrication.
