Blends of polypropylene with silver particles of controlled morphology are performed to elaborate polymer‐metal conductive composites which can present a PTC effect to be used for a specific current limited function. The samples present quite low percolation threshold around 22% in volume of Ag and a resistivity at room temperature around 100 ohm.cm. Looking at the results of the analysis of the PTC effect, it can be observed that the electrical behaviour of the samples is depending of the crystalline morphology of the systems which is governed by the specific nucleation effect of the silver filler on the polypropylene matrix.
