Carbon black (CB) fillers were used to study the feasibility of achieving multiple percolation using an immiscible (polar) polymer blend matrix. By tailoring the morphology of the insulating dual phase matrix it has been shown that the percolation threshold (Фc) can be reduced over single-phase matrices. Cocontinuity in the polymer matrix is important in reducing Фc by either preferentially isolating the conducting filler at the interface of the two phases or within one particular continuous phase of the matrix thereby forming a continuous conducting network within a continuous network (multiple percolation). Actual melt processing time has been found to influence the dispersion of the fillers and hence Фc. Polarity of the matrix as well as the processing method has also been found to influence the dispersion of the filler within the host polymer.
