Abstract EN
A.C electrical conductivity and dielectric properties for poly (vinyl alcohol) (PVA) /poly (ethylene oxide) (PEO) blends undoped and doped with multi-walled carbon nanotube (MWCNTs) with different concentrations (1, and 3 wt %) in the frequency range (25x103 - 5x106 Hz) were investigated.
Samples of (PVA/PEO) blends undoped and doped with MWCNTs were prepared using casting technique.
The electrical conductivity measurements showed that σA.C is frequency dependent and obey the relation σA.C =Aωs for undoped and doped blends with 1% MWCNTs, while it is frequency independent with increases of MWCNTs content to 3%.
The exponent s showed proceeding increase with the increase of PEO ratio (≥50%) for undoped blends samples, while s value for doped blends exhibits to change in different manner, i.e.
s increases and reach maximum value at 50/50 PVA/PEO, then decreases for residual doped blends samples with 1% MWCNTs on the other hand the exponent s decrease and reach minimum value at 50/50 PVA/PEO for samples doped with 3% MWCNTs, then return to increase.
The results explained in different terms.
