准一维纳米材料是指在两维方向上为纳米尺度,长度为宏观尺度的新型纳米材料。这种材料研究历史接近30年,早在1970年法国科学家就首次研制出直径为7纳米的碳纤维。1991年日本首次用高分辨电镜发现了碳纳米管。我国科学家解思深等人实现了碳纳米管的定向生长,并成功合成了世界上 Quasi-one-dimensional nanomaterials refer to nanomaterials in the two-dimensional direction and macroscopic-length nanomaterials. This material has a history of nearly 30 years. As early as 1970, French scientists first developed carbon fiber with a diameter of 7 nanometers. In 1991, Japan first discovered carbon nanotubes with high-resolution electron microscopy. Our scientist Xie Si and others achieved the directional growth of carbon nanotubes and successfully synthesized the world
