摘要
利用不同方法制备了Ti、ZrN、TiO2、DLC、MPC、TiN以及CNX7种薄膜。利用静滴接触角/界面张力测量仪测量了这7种薄膜与丙三醇、甲酰胺、溴代萘三种液体的固液接触角;根据测得的接触角计算了薄膜的表面自由能,并进一步比较了它们与血液的界面张力。结果表明:MPC和CN0.10薄膜具有较低的固体表面自由能,Ti、ZrN和TiO2薄膜与血液组分界面张力值相对较低。CN0.10薄膜对于纤维蛋白原的吸附较少,与血液组分交互反应也较弱,是潜在的抗凝血材料。
Thin films of seven materials （Ti, ZrN, TiO2, DLC, MPC, TiN and CN0.10） were deposited by different deposition systems. Contact angles of the seven thin films were analyzed using static drop contact angle/interfacial tension tester with glycerol, formamide and α-bromonaphtalene, respectively. According to the contact angles, surface energy of the seven films was calculated. Interfacial tension with blood components of the seven films was also compared with each other. The results show that thin films of MPC and CN0.10 have lower surface energy than others. Lower interracial tension is found in. thin films of Ti, ZrN and TiO2. With less adsorbed fibrinogen and weaker interaction with blood components, CN0.10 could be the potential anti-coagulating material.
