Piezoelectric and Dielectric Characterization of MWCNT-Based Nanocomposite Flexible Films

Figure 18

Conductivity measurements at 2 kHz for (A) corona poled and (B) contact poled bulk and thick film composites show a sharp rise in the values around a MWCNT volume fraction change from 5 to 6% which is predicted to be the region of percolation threshold from the previous piezoelectric and dielectric characteristics of the composites.
