In the present study, novel conductive PANI/thermoplastic matrices, binary and ternary blends were developed through melt blending. The binary blends' investigation focused on their morphology in light of the interactions between the components, and on the resulting electrical conductivity. Similar solubility parameters of the two components lead to fine PANI particles dispersion within the matrix, and to formation of conducting paths at low PANI contents. The morphology of a conducting network is described by a primary structure of small dispersed PANI particles, interconnected by a secondary, short range fibrillar structure. Ternary blends presently studied consist of two immiscible thermoplastic polymers, forming a co-continuous phase morphology, and PANI. The PANI preferably locates in one of the co-continuous matrix phase, affecting therefore, the blend's morphology. This concentrating effect enables relatively high electrical conductivity at a low PANI content. The blending sequence slightly affects the blends morphology and electrical conductivity.
