摘要: 将氧化石墨烯(GO)作为一种前驱体,利用3氨丙基三乙氧基硅烷(APTS)将纳米氧化钛(TiO2)接枝到GO表面来制备GOTiO2复合粒子;然后分别将2%(质量分数)的GO,TiO2,GOTiO2加入到环氧树脂(EP)中,制备复合环氧树脂涂料。利用傅里叶红外光谱仪(FTIR)、X射线衍射仪(XRD)、扫描电子显微镜(SEM)等测试方法进行表征,对制备的复合环氧树脂涂料进行电化学阻抗测试(EIS)。结果表明:GOTiO2复合粒子不仅在环氧树脂中有很好的分散性和相容性,而且能够很大程度的增强环氧树脂的耐蚀性。

Abstract: GOTiO2 was prepared by grafting nanotitanium (TiO2) onto GO surface using 3aminopropyltriethoxysilane (APTS).And then 2% of GO, TiO2 and GOTiO2 were added into the epoxy resin to prepare composite epoxy resin coating. The structure of hybrids can be measured by FTIR, XRD and SEM. The electrochemical impedance tests were carried out on the prepared composite epoxy resin coatings. The results show that GOTiO2 composite particles not only have good dispersibility and compatibility in epoxy resin, but also enhance the corrosion resistance of epoxy resin to a great extent.
