摘要:
采用热回流法,以对苯二胺为改性剂,以氧化石墨烯为原料,制备了褶皱结构的功能化石 墨烯,并对其进行了X线衍射、红外光谱、热重、拉曼光谱和X线光电子能谱分析.阐释了功能 化石墨烯的改性机理.在金属表面制备了功能化石墨烯增强的聚乙烯醇缩丁醛复合涂层,对其 防腐性能进行了测试.结果表明,功能化石墨烯的加入可以有效地提高复合涂层的抗渗透 性,FGO-0.4涂层经过120 h腐蚀之后,电解质溶液并未渗透到涂层/金属界面且具有最高的阻 抗模量.通过光学显微镜观察,几乎没有腐蚀区域产生.
Abstract:
Functionalized graphene(FGO)with wrinkled structure was prepared by thermally refluxing p-phenylenediamine(PPD,modifier)and graphene oxide(GO,raw material).GO and FGO was analyzed by X-ray diffraction,infrared spectroscopy,thermogravimetry,Raman spectroscopy,and X-ray photoelectron spectroscopy,and the mechanism of GO functionalization with PPD was explained.A functionalized FGO-reinforced polyvinyl butyral composite coating was prepared,and its anticorrosive properties were tested with electrochemical impedance spectroscopy.The results show that the addition of FGO effectively improved the permeability resistance of the composite coating.For appropriate loading of FGO in the polymer(0.4%),the electrolyte solution(NaCl)did not penetrate into the coating/metal interface.When compared with samples of other FGO concentrations,this sample exhibited the highest impedance modulus after 120 h of corrosion testing,and corrosion areas were not observed when the samples were examined by an optical microscope after exposure to air after weeks.
