Piezoelectric and Dielectric Characterization of MWCNT-Based Nanocomposite Flexible Films

Figure 4

SEM micrograph images of (a) agglomerated MWCNTs after ultrasonication with 40 ml of ethanol for 30 minutes. Piezoelectric composite films with MWCNT content equal to (b) 36.4 mg (3% in volume of the final PZT-Epoxy-MWCNT mixture), (c) MWCNT = 72.9 mg (6% in volume of the composite PZT-Epoxy-MWCNT mixture), and (d) MWCNT = 109.35 (9% in volume of the final composite mixture).
