美国加利福尼亚大学伯克利分校的科学家用碳纳米管研制出电动机,它的直径约为500纳米,仅相当于人的发丝的1/300。电动机能够在电压驱动下转动,电动机的旋转叶片是一片金叶,长度不到300纳米,叶片安装在一根由多层碳纳米管做成的转轴上。这种纳米电动机容易驱动、运动灵活,对温度 Scientists at the University of California, Berkeley, developed a motor using carbon nanotubes that are about 500 nanometers in diameter, which is about 1/300 of a human hair. The motor can rotate under voltage. The rotating blade of the motor is a gold leaf, less than 300 nanometers in length. The blade is mounted on a rotating shaft made of multi-walled carbon nanotubes. This nano motor is easy to drive, sporty and flexible to temperature
