PVA:PANI/CuI thin film composites were prepared by adding (CuI) nanoparticles to the blend of the poly vinyl alcohol and conductive polyaniline with various concentrations (0, 2, 4, 6, and 8% wt) using the casting method technique on glass substrate at room temperature. The type, concentration of charge carriers, and Hall mobility (µ H ) had estimated from Hall measurement and shown that the polymer thin films before additive of CuI nanoparticles were positive Hall coefficient (P-type). While the polymer thin films for all concentration of CuI nanoparticles have negative Hall coefficient (n-type) except of sample with concentration 6 %wt was remained positive Hall coefficient (P-type). In D.C measurement, increasing of temperature value leads to reduce the electrical resistance, also the D.C conductivity of the thin film composites rises with increasing additive concentration of CuI nanoparticles. The activation energy values for PVA:PANI polymer blend composites decreased when the concentration of CuI nanoparticles increased. Alternating electrical conductivity (σ ac ) increases when the frequency of all samples increases. While the alternating electrical conductivity (σ ac ) remains constant at very low frequency.
