| 摘 要： | 在聚氨酯(PU)中加入一定量的醋酸洗必泰-蒙脱土(CA-MMT)纳米抗菌剂,制备剥离弥散型的PU/CA-MMT抗菌材料。通过热重分析(TG)、原子力显微镜(AFM)、扫描电镜(SEM)、细菌粘附、贴膜抗菌实验等进行表征和测试抗菌性能。细菌粘附实验结果表明,相比于CA,MMT的加入使CA-MMT耐高温性能明显提高,能适应高温的加工条件,同时由于CA-MMT在材料中被剥离,易于释放出来,因此PU/CA-MMT的抗菌效果更优异。贴膜抗菌实验结果表明,未加CA的菌落数太多,无法计数;而含CA的,有明显的抗菌性,且PU/CA-MMT材料使PU基体具有良好抗菌性能,同时抗菌性能比PU/CA更优异。

| Abstract: | A peel-dispersion polyurethane/chlorhexidine acetate-montmorillonite （ PU/CA-MMT ） antibacterial material was prepared by CA-MMT nano-antibacterial agent mixed with PU. It was characterized by TG, AFM, SEM test. The antibacterial properties were tested by the bacterial adhesion and film antibacterial experiment. The bacteria adhesion experimental results showed that, compared for the CA, adding MMT could make the CA-MMT resistance high temperature performance significantly improved. It could be adapted in high temperature. The CA-MMT had more excellent antibacterial properties because CA-MMT was stripped and released from the material more easily. The antibacterial experiments result showed that, the experimental group which didn.t adding CA had many colonies, while adding CA group had few bacteria. The PU/CA-MMT nano-antibacterial material had good antibac-terial properties which was excellent than PU/CA. |
