Cartilage-bioinspired tenacious concrete-like hydrogel verified via in-situ testing.

ABSTRACT: Polyvinyl alcohol (PVA)/polyethylene glycol (PEG) hydrogels, being low-cost and abundant materials, can demonstrate tremendous potential in applications requiring mechanical robustness by harnessing the enhancements afforded by a structure inspired by articular cartilage (AC). This study presents the fabrication of bioinspired PVA/PEG (BPP) hydrogel, characterized by their high mechanical strength and low friction coefficient. By utilizing a concrete-like structure composed of PVA particles and PVA/PEG fibers, the BPP hydrogel demonstrates notable properties such as high compressive strength (86%, 29.5 MPa), high tensile strength (265%, 10.5 MPa), fatigue resistance, impact resistance, and cut resistance. Moreover, under submerged conditions, it exhibits low coefficient of friction (COF) a
