Investigating the lubrication performance of cellulose nanocrystals (CNCs) in hyaluronic acid (HA) suspensions: Analysis of rheological, tribological, and anti-corrosion properties

Biological lubricants are essential for the effective functioning of biomedical systems that involve relative motion. Hyaluronic acid (HA) is often used for its excellent lubrication properties; however, its long-term effectiveness is compromised by its tendency to accelerate metal corrosion. Incorporating cellulose nanocrystals (CNCs) into HA offers a promising solution due to CNCs' corrosion-inhibition properties, tunable rheological behavior, and tribological properties. This study examines t
