Abstract


 

ABSTRACT

samples have been prepared by adding Titanium carbide  nanoparticles to the Poly(methyl methacrylate) and  Ethylene-alpha olefin  co-polymer(SPO) and Polystyrene(PS) with different weight percentages (o, 2, 4,6 and 8) wt%. . The FTIR analysis,electrical,dielectric , and structural properties have been studied.The dielectric loss and The dielectric constant  decrease with  increasing of Titanium carbide (TiC) nanoparticles . The A.C electrical conductivity increases with increasing of Titanium carbide (TiC) concentrations and frequency. The D.C electrical conductivity  increases with increasing of Titanium carbide (TiC) concentration and temperature. the  Activation energy decreases with increasing of Titanium carbide (TiC) nanoparticles. The Humidity  sensor application of  showed that the electrical resistance of  (PMMA-SPO-PS-TiC) nanocomposites decreases with increase the Humidity.
