美国Cincinnati大学的科学家们最近制造出了世界上最长的碳纳米管。这种纳米管为阵列形式,每个碳纳米管长度略小于2cm,是其直径的九十万倍。科学家们用化学气相沉积(CVD)技术——一种通常在半导体工业中用来制造薄膜的技术——将一种新型的基底和催化剂相结合,使碳在其上沉积, Scientists at the University of Cincinnati in the United States recently created the longest carbon nanotube in the world. The nanotubes are in the form of an array, each having a length of slightly less than 2 cm, which is 900,000 times its diameter. Using chemical vapor deposition (CVD), a technique commonly used to make thin films in the semiconductor industry, scientists combine a novel substrate with a catalyst to deposit carbon on it,
