摘　　要：YBCO薄膜在液氮温区具有优异的性能,围绕低成本溶液沉积技术和新型添加剂的研究是目前研究热点.采用化学溶液沉积技术成功制备出氧化石墨烯掺杂YBCO薄膜。通过在YBCO前驱液中引人氧化石墨烯,改变YBCO胶体的热解行为,促进YBCO前驱体的分解.在晶化过程中,氧化石墨烯有利于抑制YBCO晶粒长大.结果表明,适量添加氧化石墨烯可以改善YBCO薄膜的微观形貌和外延生长,提高超导层的性能.YBCO films had shown the excellent performance under liquid nitrogen temperature.The low-cost solution deposition technologies and new additives were attractive.Graphene oxide doped YBCO films had been successfully prepared by chemical solution deposition.The decomposition and crystallization of YBCO gel were influenced by the addition of graphene oxide(GO)in the precursor solutions.GO might be useful for the growth of small YBCO grain.The results showed that the optimal addition of GO would modify the surface microstructure and the epitaxial growth of YBCO film.It could improve the performance of YBCO film.
