Abstract
The electrical resistivity and mechanical properties of carbon black ( CB)-filled polystyrene (PS)/styrene-butadiene block copolymer (SB) ble nds have been studied. Good electrical performance was achieved with p ure SB and PS/SB blends indicating an inhomogeneity of these materials and the heterogeneous micro-dispersion of the CB particles. The perco lation threshold of the filler inside SB or PS/SB blends is around 3.6 wt%, which is lower than that expected for incompatible PS/PBD blend. The addition of small amount CB decreases the elongation at break of P S/SB blends indicating some disturbance at the interface of these comp atible material.
