“…The better lubrication ability of CDs/PEG/CS/GP hydrogel originated from the hydrogen-bonded network structure of CDs, PEG, CS, and GP in the release solution (Figure 7c). Guo et al [82] reported a thermosensitive poly(ε-caprolactone)-PEG-poly(ε-caprolactone) (PCEC) hydrogel embedded with CNT. The PCEC/CNT composite hydrogel exhibited release-lubrication behavior while maintaining its injectability, and it showed a promising prospect of providing a slow-release lubrication effect on artificial joints.…”

“…The inorganic nanomaterials can not only help to improve the mechanical properties of polymer hydrogel through interacting with polymer chains, overcoming the poor capacity to resist external forces due to high water content but also enhance the tribological properties crediting to their rolling effect, load-carrying capacity, repairing ability [74][75][76][77]. Recently, many 0D quantum dots (e.g., carbon dots (CDs)), 1D nanowires, such as carbon nanotube (CNT) and fiber materials, 2D nanosheets (e.g., GO, MoS2, and MXene), and 3D NPs (e.g., TiO2, SiO2, and Fe3O4) have been employed to construct polymeric-inorganic composite hydrogel lubricants successfully [78][79][80][81][82][83][84].…”

Hydrogels have received extensive attention as functional lubricants because of their excellent anti-friction and anti-wear properties, tunable tribological performances, and effectiveness in alleviating lubrication failures caused by the creeping or leakage of conventional liquid lubricants owing to their semi-solid nature. This review summarizes the current research advances in hydrogel lubricants fabricated with various organic and/or inorganic gelators, including organic polymeric or supramolecular hydrogels, inorganic particles-based hydrogels, and organic polymer-inorganic particle hybrid hydrogels. We illustrate not only the design strategies for constructing high-performance hydrogel lubricants but also the tribological behavior and mechanism of different types of hydrogel lubricants and their potential applications in industrial and biomimetic fields. Corresponding outlooks and suggestions for future studies have also been proposed.

“…80 wt% of drug is released in an hour, which may induce toxic side effects and shorten the treatment period. 24 Therefore, in response to the adverse effect of burst drug release in hydrogels, researchers strived to slow down the release rate of drugs by incorporating nanocarriers into hydrogels, such as metal-organic frameworks, 25 mesoporous silica, 26 carbon nanotubes, 27 and polymeric nanospheres. [28][29][30] In recent years, gelatin nanospheres (GNs) have been widely used as drug carriers due to their excellent biocompatibility, degradability and cost-effectiveness.…”
