A.C Conductivity of (PS-PC) Blends Films


Measurements of A.C conductivity of Polystyrene and Polycarbonate(PS-PC) blends over frequency range (102-106Hz)and temperature range (293-473K) shows that the A.C conductivity fellows the empirical formula σa.c(w)=Aws,where(s) lies between (0.45880-0.6317),the σa.c(w) declared exponentially dependence on the reciprocal of absolute temperature for all samples .The activation energies (Eac) of blends samples were lower than those of pure PS and PC samples. The results were interpreted that the resistivity difference accompanied the PC addition to PS.
