Fig.4. Deposition charge (mC) (Qpg) vs. grain heights (nm) (AFM) and average thicl ness (wm) (SEM). Reprinted with permission from Ref. [104]. Copyright @ Elsevier. Ni-ferrite particles were used primarily, and the PPy-ferrite par- ticles with a composite structure were both synthesized via an oxidative polymerisation of pyrrole in an aqueous solution, which contains well dispersed ferrite particles, and an electrochemi- cal polymerisation technique in ACN. The logf (frequency (Hz)) versus logZ (impedance ({2)) plot were given for the chemically PPy-coated over MZF (1), PPy (2) and PPy-coated over Ni-MZF (3) particles (Fig. 6). The impedance decreases by increasing PPy over Ni-MZF, similar to the conductivity increase by four point probes. No appreciable change in the impedance was observed at frequencies below 103-104Hz, similar to the findings for the films described by Beladakere et al. [106]. The conductivity in this region has always been found to be constant for PPy sys- tems, and interestingly the composite PPy—Ni-MZF also does not
