As the wear and tear effects of artificial joints disturb patients after joint replacement, techniques of new lubrication materials or methods are constantly being investigated. Hydrothermal method was adopted to produce carbon quantum dots (CDs), and physically cross-linked polyvinyl alcoholpolyethylene glycol hydrogel (PVA-PEG) to encapsulate CDs, which was evaluated as a lubricant for lubrication appraisal with their slow-release solution. Results of the friction experiment showed that the addition of CDs changed the structure of the gel and promoted the tribological properties of the gel. The structural characterization results show that the CDs are successfully wrapped in gel. The network cross-linked structure of the gel is improved due to the addition of CDs, which are shown by the results of thermogravimetric analysis (TGA) and differential scanning calorimetry analysis (DSC). At the same time, CDs can influence the thermal stability and crystallinity of the gel as well as the degree of cross-linking. These results of TGA and DSC suggest that the curled molecular chain will not be stretched during the gel cross-linking process. After 2 h of self-healing, the recovered gel did not break again under the pull of external force. All these contribute to the preparation and application of hydrogels which is worth looking forward to accelerate the development of polymer lubrication.

“…Composite materials, such as polymer‐polymer combinations, can produce hydrogels with better and desirable properties than those made from a single material, and these hydrogels can be intentionally modulated. Polyethylene glycol (PEG) is a biopolymer with a wide range of applications, having flexible COC chains, 23 being a component of artificial cartilage, as well as being well water soluble, nontoxic and immunologically inert, at the same time, providing good self‐lubricating properties as an important lubricant, and has been approved by the Food and Drug Administration for in vivo use as a biomacromolecular material 24 . Several investigations have increasingly shown that reactive oxygen species are a major cause of osteoarthritis, and Chen et al found that the addition of PEG showed significant improvement in scavenging reactive oxygen species as well as significant repair of articular cartilage structure 25 .…”

Polyvinyl alcohol (PVA) hydrogels have potential applications in bionic articular cartilage due to their good biocompatibility and low friction. However, the lack of adequate mechanical properties is a key obstacle for PVA hydrogels to replace natural cartilage. In this study, polyethylene glycol (PEG) was introduced into the PVA hydrogel, and the (PVA/PEG) composite gels were prepared by a blending physical cross-linking method. The PVA/PEG gels were treated with a simple and novel organic solvent immersion dehydration to improve its mechanical and tribological properties. And the using of organic solvents for dehydration changed the network structure of the PVA/PEG gels, which improved the mechanical properties effectively. In this study, the effects of different organic solvents on the tribological properties, swelling ratio, shore hardness, and dehydration rate of PVA/PEG hydrogels were investigated. Compared with natural drying, organic solvent dehydration reduced the gel formation time. Notably, the organic solvent dehydration treatment reduces the wear rate of PE ball friction pair to 27.4% of the original amount, improving wear resistance. Meanwhile, self-healing and cellular immune assays demonstrated the excellent biocompatibility and self-healing ability of the PVA/PEG gels.This study provides a new candidate material for the design of articular cartilage, which is expected to advance the progress of artificial cartilage repair.

With their excellent properties, hydrogels have attracted much attention for their potential application. However, it is still necessary to study the influencing factors of the hydrogel preparation process and its self‐healing mechanism. In this paper, the preparation method of boric acid (BA) cross‐linked poly(vinyl alcohol) (PVA)/hyaluronic acid (HA) hydrogel appeared to become studied in order to explore the effect of pressure in the cross‐linking process. Associated with, PVA and HA were combined, and then the mixture was cross‐linked with BA to produce BA‐PVA/HA hydrogel. The state of the hydrogel after cross‐linking was transformed after centrifugal pressure method, and its performance was analyzed experimentally. Compared with the BA‐PVA/HA hydrogel without centrifugal supercharging, the hydrogel after centrifugation has lower water content and lubricating effect, and the surface hardness is improved at the same time. In addition, the BA‐PVA/HA hydrogel has no external stimulation at room temperature, can also self‐heal quickly have based on hydrogen bonds, and has good recyclability. These results indicate that adding centrifugation steps in the preparation of BA‐PVA/HA hydrogels could properly switch the state of the hydrogels, which is expected to provide a certain research basis for the preparation and application of hydrogels.
