Abstract:Inspired by the excellent wear resistance and lubrication of articular joints, a novel bionic interfacial system was proposed by combining thixotropic hydrogel with surface porous Ultrahigh Molecular Weight Polyethylene (UHMWPE). Thixotropic hydrogel, synthesised by gelatin, alginate sodium, tannic acid and weak crosslinking by Ca2+ (Gel‐TA‐Alg@Ca2+), was used as a lubricant due to its shear‐thinning when loaded, then the recovery viscosity to be benefitted for reserving in surface pores on UHMWPE when unloade… Show more
