GOPMO复合材料的制备与表征毕业论文

 2020-06-16 08:06  

摘 要

氧化石墨烯因其具有优越的导电性以及各项条件,被看好为复合材料作用。我们把它与超级电容器中的单一电极材料复合的时候,可以显著增进强化电容器的种种数据强度。本文采用了浸泡法作为唯一的实验方法(非测量方法)与传统且众所周知的Hummers法,分别制备石墨烯成品与氧化石墨烯、氧化石墨烯磷钼酸复合材料。并进一步将氧化石墨烯在饱和磷钼酸溶液中进行长时间的浸泡(大于24小时)并且将他们表征。通过SEM扫描电镜、XRD-X射线衍射实验、FTIR傅立叶红外测试,来获得各项基础数据,该实验结果表面磷钼酸粒子在植入过程里面其三个端氧和氧化石墨烯片层表面的含氧官能团通过氢键发生作用,经过空间位置、方法的调整降低其表面位能并最终附着于GOxD 片层表面。我们将之放入origin软件站中制成图表,对照参考,以研究其各项性能。X射线衍射实验的结果是:氧化石墨烯磷钼酸复合材料的XRD特征衍射峰的峰位和氧化石墨烯的峰位几乎相等。因为磷钼酸离子大约宽为0.97纳米,这个数值和氧化石墨烯的层间距相当,于是证明了一个事实:氧化石墨烯在饱和的磷钼酸中长时间浸泡后磷钼酸离子没有嵌入氧化石墨烯片层中。而另一面,在FTIR测试中,氧化石墨烯在磷钼酸饱和溶液中进行长时间的浸泡(大于一天一夜)所获得的氧化石墨烯磷钼酸复合材料样品里的磷钼酸离子和氧化石墨烯片的表层产生了剧烈反应并且能够植入氧化石墨烯片层内。

第一章首先概述了石墨烯的概况。简明扼要地阐述了石墨烯的形状,状态,还有石墨烯所具有的所有的物理性质。并介绍了自上世纪年以来石墨烯的主要研究方向及其应用前景。

第二章重点介绍了采用浸泡法制备石墨烯,及其所需条件、实验器材。

第三章首先简要的介绍了氧化石墨烯的制备及其表征。然后将磷钼酸复合到石墨烯上,并对其进行电学及其光学测量。

第四章对本实验作了总结,并分析其不足及需要改进之处。我们也对氧化石墨烯磷钼酸复合材料的生长机制进行了猜想,并提出了一些基本假设。

关键词:氧化石墨烯;氧化石墨烯磷钼酸复合材料;浸泡法;扫描电镜。

Abstract

Oxidized graphene because it has excellent conductivity and the conditions, is optimistic about the role of composite materials. When we compounded it with a single electrode material in a supercapacitor, it is possible to significantly improve the level of the supercapacitor. In this paper, the impregnated and traditional Hummers method were used to prepare graphene finished products with graphene oxide and graphene molybdic acid. And make them characterized. Through the SEM scanning electron microscope, XRD-X-ray diffraction experiment, FTIR Fourier infrared test, to get the basic data, we put the origin software station made in the chart, the reference to study its performance.

The first chapter outlines the overview of graphene first. The structure of graphene and its basic physical properties are briefly introduced. This paper introduces the main research direction of graphene and its application prospect since the last century.

The second chapter focuses on the preparation of graphene by immersion method, and its requirements, experimental equipment.

The third chapter first briefly introduces the preparation and characterization of graphene oxide. The phosphomolybate is then compounded to the grapheme, and carries on the electrical and optical measurements.

The fourth chapter summarizes the experiment and analyzes its shortcomings and where it needs to be improved. We have also hypothesized the growth mechanism of the graphene phosphomolybdic acid composite and proposed some basic assumptions.

Keywords: graphene oxide; Graphene phosphite compound material; Immersion method; Scanning electron microscopy (sem).
