A self-healing bio-lubricating hydrogel coating synergistically enhanced with ZIF-8 nanoparticles, exhibiting corrosion resistance, antibacterial properties, and wear resistance
Hydrogel is an ideal material for replacing natural articular cartilage. However, their inadequate mechanical properties, such as severe dynamic damage, restricted its application in the field of joint replacement. Herein, based on Schiff base bond (dialdehyde starch (DS) with acrylamide (AM)) and metal coordination bond (Fe3+ with DS), we designed a self-healing bio-lubricant hydrogel coating (DS/AM/Fe3+). Moreover, the nano-composite metal-organic framework (ZIF-8) was applied to the DS/AM/Fe3+ hydrogels to improve its mechanical properties. The 1000ppmZIF-8/DS/AM/Fe3+ hydrogel coatings show excellent tribological properties and corrosion resistance, with wear rate reduced by 32.94%, friction coefficient reduced to 0.104, corrosion inhibition efficiency up to 79.63%, and active antibacterial and biological activity. The designed hydrogel provides potential applications for artificial joint replacement.
