Piezoelectric and Dielectric Characterization of MWCNT-Based Nanocomposite Flexible Films

Figure 11

Cross-sectional SEM micrograph of a PZT-Epoxy-MWCNT thick film with MWCNT volume fractions of (a) 0.04 (4%) and (b) 0.06 (6%) showing the thick film of thickness ~150 μm spin coated over a flexible stainless substrate of thickness 20 μm. (c, d) The SEM micrographs of the fractured surface of the three-phase composite with MWCNT volume fractions of 0.04 (4%) and 0.06 (6%). They show the distribution of the PZT clusters and MWCNT clusters in the epoxy matrix.
