Figure 4-12. a) Schematic representation of quinary multi-percolated morphology, the yellow<br />

phase is PANI, the blue phase is HDPE, and all other phases are located between them, b)<br />

schematic of a PANI network obtained after removal of all phases except PANI, and c) a 3D<br />

image constructed from 2D SEM images of the interconnected PANI network in the quinary<br />

15/20/15/25/25 PS/PS-co-PMMA/PMMA/PVDF/PANI blend after extraction of all other phases.<br />

This figure clearly confirms that in a triple-percolated structure with PANI as the inner phase,<br />

PANI will spread. As shown in Figure 4-11e, the PANI network in a multi-percolated structure<br />

has branches with very thin walls. The range of thicknesses of the wall in this structure range<br />

from a few hundred nanometers to 700 nanometers. Another important point that should be taken<br />

into account is the actual content of pure PANI in the blends. The PANI used in this work is<br />
