ZnO/Ag复合抗菌剂的改性及在医用PVC中的应用

Key Words:ZnO/Ag;;钛酸酯偶联剂TC-27;;医用抗菌PVC
 Abstract:用钛酸酯偶联剂TC-27对ZnO/Ag复合抗菌剂进行表面改性,并分别以改性前后的抗菌剂为功能添加剂制备出抗菌PVC,考察了表面改性及抗菌剂用量对抗菌PVC力学性能及其抗菌性能的影响。研究表明,以TC-27对ZnO/Ag复合抗菌剂进行表面改性能够提高复合抗菌剂的活化率,增强其亲有机相程度,从而使抗菌PVC的拉伸强度和断裂伸长率均优于普通PVC;表面改性对抗菌PVC的抗菌性能影响不大;当ZnO/Ag复合抗菌剂的添加量达到3%(质量分数)时,抗菌PVC对大肠杆菌和金黄色葡萄球菌的抗菌率均超过90%。
