AbstractRare SWCNT materials contain both metallic SWCNT (m-SWCNT) and semi-conducting SWCNT(s-SWCNT). Since m-SWCNT and s-SWCNT have very different applications, it is necessary to differentiate them so as to further separate them for more efficient CNT utilization. To achieve this goal, the authors established a dielectric force microscope (DFM) detection system to differentiate s-SWCNT from m-SWCNT, based on different 2ω force decided by SWCNT's conductivity under AC electric field. The experimental results showed that s-SWCNT can be clearly differentiated from m-SWCNT. The statistics analysis shows that the detected number proportion of s-SWCNT to m-SWCNT matches the well-known proportion 2:1 in the normally prepared CNT materials. The above results strongly verified the effectiveness of the detection system.
