Improvement of some electrical properties for PS-TiO2 composite

Abstract EN

In this research the effect of filler content on improving some electrical properties of polystyrene filled with TiO2 powder has been studied.

For that purpose, the polystyrene (PS) samples with TiO2 additive prepared with different percentages (0, 5, 10, 15, 20, 25, 30) wt.

%.

The results show that the D.C electrical conductivity of such composite improved about 52 % when the concentration of TiO2 is increased.

Also the results show that the dielectric constant, dielectric loss, are improved about 51 %, 77 % respectively, and A.C electrical resistivity are changed with changing the concentration of the filler and frequency of applied electrical field, that means the A.C electrical conductivity of PS-TiO2 is improved about 86 %.

The results show good improvement in electrical properties of this research that agreed with theoretical principles.
