a FT-IR spectrum and b XRD pattern of PZT, PZT-1 and PZT-3 particles, c-h EDS and element mapping of the PZT@MgO particles
Source publication
Polymer dielectrics with synergistic large dielectric constant (ε′) and high breakdown field strength (Eb) have important applications in electronics device and electrical industry. In this work, to enhance the integrated dielectric characteristics of lead zirconate titanate (PZT)/poly(vinylidene fluoride) (PVDF), an insulating magnesia (MgO) shell...

... of PZT@MgO particles Figure 2a shows the FT-IR spectra for pure PZT and various PZT@MgO particles, respectively. The vibration of -OH groups on the particle surfaces can be connected to the absorption peaks at 3437 cm −1 . ...

... XRD patterns for both the pure PZT and the coreshell structured PZT particles are shown in Fig. 2b. Each XRD pattern has three significant peaks at 21.2°, 30.7°, 38.3°, 45.2° and 54.6°, corresponding to the (100), (110), (111), (200) and (211) lattice planes of PZT particle, respectively. Besides, additional diffraction peaks at 42.9° and 62.2° in the PZT@MgO particles arise in comparison to the pure PZT particles and are compatible ...

... can be shown in Fig. 2c-h, evidently, the results from FT-IR and XRD analyses are similar with the EDS mappings, which show that the surface of samples is composed of Pb, Zr, Ti, Mg, and O elements. Also, the even distribution of the Mg and O elements suggests that a uniform MgO shell has been generated on the surface of raw PZT particles [31]. In contrast to ...
