摘　　要：从Cu-Al二元相图出发,设计具有层片状共晶结构的前驱体合金Cu12Al88,发展合金化/脱合金化技术可控制备了兼具大孔(约150 nm)和小孔(约15 nm)的双模式纳米多孔铜。研究结果表明:相对于非共晶结构制备得到的单模式纳米多孔铜,该双模式纳米多孔铜表现出显著增强的热力学结构稳定性。基于科研项目的开放性创新实验,结合材料科学基础知识,利用新技术发展新材料,可以加深学生对基础知识的理解,培养学生对基础知识的应用能力和创新能力,同时也有利于提高其科研兴趣。According to the Cu-Al binary phase diagram, precursor Cu12 Al88 alloy sheets with lamellar structure are designed, the alloying/dealloying technology is developed, and the bimodal nanoporous Cu with macro pores(about 150 nm) and small pores(about 15 nm) is prepared. It demonstrates that compared with the single-modal nanoporous Cu prepared by dealloying non-eutectic alloy, the bimodal nanoporous structure enables nanoporous Cu exhibits remarkably enhanced thermodynamic stability. The open innovation experiment based on scientific research projects, combined with the basic knowledge of materials science, and by using new technology to develop new materials, can deepen students’ understanding of basic knowledge, cultivate their application ability and innovation ability of basic knowledge, and also help to improve their interest in scientific research.
