    Nano-sized BaSrTiO3 particles and a dispersant were incorporated in samples of low density polyethylene (LDPE). The nanoparticle loading was 2 or 10 by weight (w/w), and the dispersant loading was 4 parts per hundred relative to BaSrTiO3. dc conductivity measurements were made in the temperature range 30-70 A?C in vacuum, and in air at 30 A?C. The vacuum dc conductivity in samples containing only the dispersant (0.4 ) was approximately five times larger than that in LDPE samples without additive, but approximately an order of magnitude larger than that in samples containing 10 nanoparticles and 0.4 dispersant. Addition of 10 nanoparticles and 0.4 dispersant increased I?a??, the real part of the relative permittivity, from approximately 2.34 to around 2.58 at 30 A?C, in air and in vacuum.
