Abstract:Polyurethane (PU) has been used in clinical practice for artificial meniscus to alleviate the distress of patients with meniscus injury, but the high friction of PU in synovial fluid can lead to the deterioration of knee joints. In this work, PUs with sulfobetaine zwitterions modified by hydrophobic chains in bulk (PU-hSBs) are synthesized to solve the above-mentioned challenge, and the lubrication behavior and mechanism of PU-hSBs in the aqueous solution of representative synovial components that mimic the in… Show more
