    Abstract: (PS-SPO-Ag) nanocomposites prepared by adding silver nanoparticles to the Polystyrene (PS) and ethylene alpha olefin copolymer (SPO) with different percentages (0, 3, 6, 9 and 12) wt.% . The AC electrical conductivity (&sigma;<sub>ac</sub>) increases with increasing of silver (Ag) concentrations and Frequency (F). The DC electrical conductivity (&sigma;<sub>dc</sub>) increases with increasing of silver (Ag) concentrations and Temperature (T).The dielectric loss and the dielectric constant (&#941;) decrease with increasing of silver (Ag) nanoparticles. The activation energy (E<sub>act</sub>) decreases with increasing of silver (Ag) nanoparticles. The pressure sensors application showed that the electrical resistance of (PS-SPO-Ag) nanocomposites decreases with increasethe pressure.
