Blood-compatibility of PLA/Liquid Crystal Composite Membranes

摘要

In this paper we synthesised hydrophilic liquid crystal, cholesteryl triethenyl glycol carbonate (TCC), which were blended with PLA with certain contents to form composite membranes. The blood-compatibility of the composite membranes was assessed from blood clotting time and hemolysis ratio which showed that these PLA/liquid crystal composite membranes with the content of 30%, 40% liquid crystal appeared to be beneficial in improving the blood compatibility and reducing the thrombogenicity.
