FC／ZnO杂化材料的制备及结构与性能

采用射频磁控溅射法,分别以聚四氟乙烯(PTFE)和锌为靶,在聚对苯二甲酸乙二醇酯(PET)基底上沉积氟碳(FC)膜以及FC/ZnO的有机-无机纳米杂化材料。用SEM、UV、XPS对氟碳膜和杂化材料进行了表征。结果表明,氟碳膜形成了一种由纳米粒子-纳米孔洞组成的双纳米结构,随着ZnO沉积时间的不同,FC/ZnO杂化膜呈现出不同的表面形貌,杂化膜的生长模式是一种依附于有机核的沉积-扩张生长模式;杂化材料的F/C较低,随着氧化锌沉积时间的增加,F/C出现逐渐增大的趋势;杂化膜是一种多重抗紫外线辐射的功能膜。

Preparation,Structure and Properties of Hybrid FC/ZnO Material

Fluorocarbon films and hybrid FC/ZnO materials were prepared by R.F.magnetron sputtering on PET substrate.The polytetrafluoroethylene(PTFE) and zinc were used as target respectively.Fluorocarbon films and hybrid FC/ZnO materials were characterized by means of SEM,UV and XPS.It is found,at certain sputtering conditions,fluorocarbon films form a regular structure that both particles and holes are nanometer size.The surface morphology of hybrid FC/ZnO films varies as the deposited time of ZnO.The growing mode of hybrid films is a deposition-expansion adhering to the organic core.The hybrid films are highly cross-linked unsaturated and low F/C.F/C ratio increased with the deposited time of ZnO increases.The hybrid films exhibit multi-enhanced ultraviolet absorption property.
