摘要
利用三点弯曲法研究了不同管径的碳纳米管膜的压阻效应,实验结果表明,管径较小的碳纳米管膜与管径大的碳纳米管膜相比具有更显著的压阻效应,并对电阻随应力变化的机制作了详细的讨论。
In this paper,the size-dependent piezoresistive effect of MWNT films was investigated by a three-point bending technique. We found that films made of nanotubes with smaller diameter exhibited better performance in piezoresistive effect than that made of nanotubes with larger diameter, The cause of the stress-induced resistance in the films has been discussed in detail.
