Abstract
The solid polymer blend sample films of Poly (ethylene Oxide) (PEO)/Sodium Carboxy methyl cellulose (CMC) with 10/90, 30/70, 50/50, 70/30 and 90/10 compositions were prepared by solution cast technique and electrical properties were investigated by Dielectric studiesassociated with dielectric constant (ɛ′ ) and dielectric loss (ɛ′')including AC conductivity (σac) measurements. Dielectric constant and dielectric loss are found to decrease with the increase of frequency, and laterremains constant for all blend compositions in higher frequency range. Conductivity studyreveals that,the blend of 10/90 composition exhibits higher electrical conductivity of 2.707X10−5 Sm−1 and is found to be decreased with increase inwt.% of CMC in the blend matrix. The deviation in the trend of conductivity has been observed at 70/30 and 90/10 composition due to the miscibility.
