由厦门大学化学系张鸿斌、林国栋两位教授带领的教研组经过近两年的研究,最近运用化学催化合成法研制出一种外径15～25纳米、内径约3纳米的多壁碳纳米管,并建立了纯化分离方法,单程产率由原先的0.1克增到10克.检索表明,该技术属国内首创,在国际上与技术尚处于保密阶段的美、荷等国比,水平也难分伯仲. After nearly two years of research, led by two professors from the Department of Chemistry, Xiamen University, Zhang Hongbin and Lin Guodong, recently, a multi-walled carbon nanotube with an outer diameter of 15-25 nanometers and an inner diameter of about 3 nanometers was developed by chemical catalytic synthesis Established a purification separation method, one-way yield increased from the original 0.1 grams to 10 grams.Research shows that the technology is a national initiative, in the international arena and technology is still in the stage of confidentiality of the United States, Holland and other countries, the level is also very close .
