Piezoelectric and Dielectric Characterization of MWCNT-Based Nanocomposite Flexible Films

Figure 9

(a, b) Diffraction pattern and TEM images of MWCNTs dispersed in ethanol after a sonication time of 4 hours. The cylindrical ring-like structures of the MWCNTs are present in (a). Even after sonication in ethanol, the TEM images indicate that some forms of agglomeration of MWCNTs still exist.
