| 摘 要： | 用混酸对多壁碳纳米管（MWCNTs）进行了酸化处理，然后通过溶胶-凝胶法制备了TiO2包覆MWCNTs（TiO2-MWCNTs）核壳材料，并通过X射线衍射（XRD）、热重分析（TGA）等手段对其包覆结果进行了验证。用硅烷偶联剂KH560对TiO2-MWCNTs及MWCNTs进行了改性，分别制备了TiO2-MWCNTs/epoxy、MWCNTs/epoxy复合环氧涂层以及纯环氧涂层，利用EIS测试了涂层的电学性能，通过材料试验机（MTS）测定了涂层的柔韧性，用扫描电镜（SEM）观察了涂层表面形貌。结果表明：TiO2-MWCNTs在环氧树脂中具有良好的分散性，TiO2-MWCNTs/epoxy复合涂层对腐蚀介质具有较好的抗渗透性能；TiO2包覆后大大增加了涂层的柔韧性。

| Abstract: | The multi-walled carbon nanotubes (MWCNTs) were acidified by mixed acid, then the MWCNTs coated with TiO2 (TiO2-MWCNTs) hybrid material were prepared by sol-gel method, and the results were verified by X-ray diffraction (XRD) and thermogravimetric analysis (TGA). The silane coupling agent KH560 was used to modify the TiO2-MWCNTs and MWCNTs, and the composite coating of TiO2-MWCNTs/epoxy resin, MWCNTs/epoxy resin and the pure epoxy coating was prepared respectively. The electrical properties machine flexibility of composite coatings were tested through EIS and material test system (MTS). Scanning electron microscope (SEM) was used to observe the coatings surface condition. The results show that TiO2-MWCNTs disperse good in the epoxy resin, TiO2-MWCNTs/epoxy composite coating in the corrosion medium has good resistance to permeation, and the flexibility of coating is increased greatly after coated by TiO2. |
