| 目的：研究磁控溅射法在聚四氟乙烯(PTFE)微孔膜上负载TiO2,制备TiO2/PTFE复合膜。方法：利用接触角、扫描电子显微镜(SEM)、X射线光电子能谱(XPS)、拉伸强度等对复合膜亲水性、元素、形貌和机械强度进行测试,通过控制变量法研究了溅射时间、溅射功率对膜性能的影响及对复合膜对甲基橙的降解性能。结果：在溅射功率为40w,溅射时间为90s时,TiO2/PTFE复合膜的亲水性和拉伸强度相对较好,甲基橙的去除率达97%,降解效果好。结论：通过实验可以优化出磁控溅射的工艺参数,制备出物理性能优异,并具有较高的光催化活性的负载型纳米催化剂。 |

| Objective Making the research about using the magnetron sputtering method load TiO2 upon polytetrafluoroethylene (PTFE) microporous membrane to prepared TiO2 / PTFE composite membrane preparation . Methods Using contact angle, scanning electron microscopy (SEM), X-ray photoelectron spectroscopy (XPS), tensile strength test the hydrophilic, elements, morp-hology and mechanical strength of the composite membranes,discussion the effects of sputtering time, sputtering power on the film properties with control variable technique as well as study the degradation towards methyl orange Results We know that the hydrophilic and tensile strength of TiO2/PTFE composite film are favorable when the sputtering power is 40w and sputtering time is 90s and the removal rat of methyl orange reach 97%, exhibiting better degradation property. Conclusion By the experiment process, we can optimize the parameters of magnetron sputtering, preparation a kind of nanometeran supported catalyst with excellent physical properties and high photocatalytic activity. |
