  • 单片层氧化石墨烯由于其优异的物理化学性能, 在离子和分子筛选、水脱盐和净化、气体分离、生物传感、质子导体、锂电池和超级电容等领域有巨大的潜在应用. 然而普遍采用的Hummers法等化学、物理方法制备的氧化石墨烯是一种亚稳态材料. 其最终形态的物理化学性能的转变与调控至关重要, 亟需系统研究. 本文采用恒温处理方法对氧化石墨烯亚稳态的转变进行调控, 利用X射线光电子吸收谱、傅里叶红外吸收谱、扫描电子显微镜等方法检测氧化石墨烯含氧基团的含量、类型和形貌与温度的变化关系, 并利用Zeta电位、紫外吸收谱、拉力测试分析温度对氧化石墨烯在转变过程中的溶液悬浮稳定性、光子能带、拉伸强度等性能的影响. 所得定量测试结果发现, 氧化石墨烯亚稳态的转变过程中存在环氧减少、羟基增加, 以及整体含氧量下降的现象, 而在此过程中氧化石墨烯的单片层形貌并无明显变化. 但是这种结构的转变使得悬浮液黏稠度和亲水性大幅度增强, 能带减小和拉伸强度增强效应明显. 而当转变过程足够长时, 氧化石墨烯的亲水性转而下降, 并出现沉淀现象, 表明羟基之间进一步发生了脱水转变. 另外, 本文还分析了恒温处理的时间、悬浮液的浓度对这种转变过程的影响. 相关研究结果有利于理解亚稳态氧化石墨烯悬浮液随温度变化的性能转变, 对氧化石墨烯具体应用有一定参考价值.
    Monolayer of graphene oxide has great potential applications in ion and molecular screening, desalination and purification of water, gas separation, biosensing, proton conductors, lithium batteries, super capacitors and other fields, due to its excellent physical and chemical properties. However, the graphene oxide prepared by chemical and physical methods, such as the commonly used Hummers method is a metastable material. The transformation and regulation of the physical and chemical properties of the final morphology are essential, and systematic research is urgently needed. In this paper, the thermostat treatment method is used to control the metastable transformation of graphene oxide. The relationship of content, type, and morphology with temperature of oxygen-containing graphene oxide are detected by X-ray photoelectron absorption spectroscopy, Fourier infrared absorption spectroscopy, scanning electron microscope, etc.; and the effects of temperature on the stability of solution suspension stability, photon energy band and tensile strength of graphene oxide in the transformation process are analyzed by using Zeta potential, ultraviolet absorption spectrum, tensile force. The quantitative test results show that there exists a phenomenon in which the epoxy phase decreases, the hydroxyl group increases and the overall oxygen content decreases in the metastable transition process of graphene oxide, and the monolayer morphology of graphene oxide does not change significantly in this process. This structural transformation, however, greatly enhances the viscosity and hydrophilicity of the suspension, and remarkably reduces the energy band and considerably raises the tensile strength enhancement effect. When the transformation process is long enough, the hydrophilicity of the graphene oxide will decrease and precipitate. It is indicated that a further dehydration transition occurs between the hydroxyl groups. In addition, in the paper we also analyze the effect of constant temperature treatment time and concentration of suspension on this transformation process. The relevant research results are helpful in understanding the performance change of metastable graphene oxide suspension with temperature, and have certain reference value for the specific application of graphene oxide.
