Abstract
Polyvinyl alcohol (PVA) as a green biodegradable polymeric matrix was chosen to fabricate high-k (high permittivity) polymer nanocomposites with good magnetic and electric properties to be used for electrostatic dissipation applications. PVA was doped with different concentration of magnetite (Fe3O4) nanoparticles and barium titanate (BaTiO3) nanoparticles before and after treatment with ionic liquid (IL). The magnetic properties were investigated by vibrating sample magnetometer (VSM) and the obtained results revealed an improvement in such properties by the ionic liquid treatment of BaTiO3. This finding widens the application scope of PVA nanocomposites to include electromagnetic purposes. Moreover, electrical properties including permittivity , dielectric loss  in addition to electrical conductivity  were also studied. The dielectric properties were also enhanced after ionic liquid treatment. In addition, the values of conductivity  was in the order ~ 10-7 S/cm which endorse using such nanocomposites for electrostatic dissipation applications.
