Study on Surface Grafted Chitosan Modification of LARS Artificial Ligament Material

Updated: 2018/12/27 11:20:31

Abstract: The monofilament of artificial ligament material was modified by plasma and chemical treatment methods, and the effects of chitosan concentration and chitosan graft modification time on the performance of LARS artificial ligament monofilament were investigated. The results showed that the modified monofilament had the best performance when the chitosan concentration was 2% and the modification time was 25 hours. Compared with the monofilaments without any treatment, the diameter, breaking strength and elongation at break increased by 5.2%, 4.4%, and 7.2%, respectively, and the contact angle decreased by 52.8%.
