【摘要】：多金属氧酸盐具有独特的结构和优越的电、光、磁等物理和化学性质以及潜在的应用前景逐渐引起人们的关注。如果将多金属氧酸盐与石墨烯相结合那么所形成的新型材料即具有多金属氧酸盐的性质也具有有石墨烯的性质,且二者相互影响。因此基于多金属氧酸盐与石墨烯形成的新型材料并适合各个领域需要是当今材料科学研究的焦点所在。从目前的研究形势来看,多金属氧酸盐与石墨烯形成的新型材料的研究总的来说仍然处于起步阶段,多金属氧酸盐具有丰富的种类和多样的功能性有望成为设计、制备、研究的最佳候选。大量的文献表明,石墨烯与多酸化合物形成的新型材料,具有耐腐蚀等独特物理、化学性质,因此对多酸-石墨烯材料进行研究具有重要的实际应用价值和理论意义。目前,国内外关于石墨烯与多酸化合物相互作用的研究很少,进一步研究具有多功能性质的多金属氧酸盐与石墨烯形成新型材料的制备是迫切必要的。本文以层接层法制得石墨烯/二氧化钛/多酸复合薄膜,研究其光电性质,并与分别不引入二氧化钛、多酸、石墨烯三种情况的薄膜进行对比。又凭借无模板合成法,以多酸与石墨烯为原料,通过调节pH值制得石墨烯-多酸微米管,并研究了其物理化学性质。
[Abstract]:Polyoxometalates with unique structure, excellent electrical, optical, magnetic and other physical and chemical properties, as well as potential applications of people's attention. If polyoxometalates are combined with graphene, the new materials have the properties of both polyoxometalates and graphene, and they interact with each other. Therefore, new materials based on polyoxometalates and graphene are the focus of material science research. According to the current research situation, the research on the new materials formed by polyoxometalates and graphene is still in its infancy, and the polyoxometalates are expected to be designed and prepared with rich variety and various functions. The best candidate for research. A large number of literatures show that the new materials formed by graphene and polyacid compounds have unique physical and chemical properties such as corrosion resistance. Therefore, the study of polyacid-graphene materials has important practical application value and theoretical significance. At present, there are few studies on the interaction between graphene and polyacid compounds at home and abroad. It is necessary to further study the preparation of new materials of polyoxometalates and graphene with multifunctional properties. The optoelectronic properties of graphene / titanium dioxide / polyacid composite thin films prepared by laminated layer method were studied and compared with those without titanium dioxide, polyacid and graphene respectively. The graphene polyacid micron tube was prepared by adjusting pH by using polyacid and graphene as raw materials, and its physical and chemical properties were studied.
