以含氢硅油和乙烯基硅油为基质 ,在氯铂酸催化下与胆甾醇油烯基碳酸酯液晶共混交联成一定强度的聚硅氧烷 /液晶复合膜。借助偏光显微镜观察了不同液晶含量在材料表面的状态 ,通过动态凝血实验、血小板粘附与变形实验、溶血实验等研究材料表面形态与血液相容性的关系。结果表明 ,含液晶 2 0 %、3 0 %的液晶膜具有优良的抗凝血性能。 Hydrogen silicone oil and vinyl silicone oil as a matrix, the chloroplatinic acid catalysis with cholesteryl oleyl carbonate liquid crystal hybrid cross-linked to a certain intensity of the polysiloxane / liquid crystal composite membrane. The state of different liquid crystal content on the surface of the material was observed with a polarizing microscope. The relationship between the surface morphology of the material and the blood compatibility was studied by dynamic coagulation test, platelet adhesion and deformation test, hemolysis test and the like. The results show that with 20% liquid crystal, 30% liquid crystal film has excellent anticoagulant properties.
