Fe2O3-HNTs杂化材料的制备及其对环氧树脂涂层性能的影响
Preparation of Fe2O3-HNTs hybrid Material and Its Effect on Properties of Epoxy Resin Coating
摘 要
通过化学沉淀法实现了纳米三氧化二铁（Fe2O3）在埃洛石纳米管（HNTs）表面的均匀负载，得到相应的Fe2O3-HNTs杂化材料。通过X射线衍射仪（XRD）、热重分析仪（TGA）以及扫描电子显微镜（SEM）等对负载效果进行了表征。然后利用硅烷偶联剂KH560对Fe2O3-HNTs杂化材料进行表面改性处理，并与环氧树脂复合，制得Fe2O3-HNTs/EP复合涂层。通过摩擦磨损试验、电化学阻抗谱（EIS）测试分析了该复合涂层的耐磨性及耐蚀性。结果表明：与纯环氧树脂涂层相比，Fe2O3-HNTs/EP复合涂层在耐磨性，韧性，抗腐蚀介质渗透等方面都有所提高。

Abstract
Through chemical precipitation method, nano ferric oxide particles (Fe2O3) were evenly coated on the surface of halloysite nanotubes (HNTs) to prepare Fe2O3-HNTs hybrid material. And the coating effects were analyzed with X-ray diffraction (XRD), thermogravimetric analysis (TGA) and scanning electron microscopy (SEM). Then the Fe2O3-HNTs hybrid material was further modified with silane coupling agent KH560. And the Fe2O3-HNTs/EP composite coating was prepared by mixing the modified Fe2O3-HNTs hybrid material and epoxy resin. Friction-wear experiment and electrochemical impedance spectroscopy (EIS) testing were carried out respectively to evaluate the wear resistance and corrosion resistance of the composite coating. The results show that the wear resistance, toughness and corrosion resistance of the Fe2O3-HNTs/EP composite coating were improved significantly compared with the pure epoxy coating.
