“…Due to the high dielectric constant as well as unique piezoelectric and pyroelectric properties of barium titanate (BaTiO 3 or simply BT) , its nanopowder is extensively utilized with many synthetic polymers in making high‐κ ceramic‐polymer nanocomposites for several compact capacitor applications including tunable capacitors, pyroelectric sensors, nonvolatile memories, and surface acoustic wave devices . The microstructural, mechanical, and dielectric properties of such systems have been demonstrated as well . Dielectric systems having high tetragonality BT filler demonstrated the best ferroelectric and dielectric properties, especially for application in multilayer ceramic capacitors (MLCCs) .…”

High dielectric constant BaTiO 3 /ethyl cellulose (BT/EC) nanocomposites having BT loadings of up to 13 vol% were fabricated through a simple casting technique. The BT filler powder, synthesized through an ultrasonicassisted solid-state route, was revealed by X-ray powder diffractometry (XRD) and Raman spectroscopy to be dominantly tetragonal. Scanning electron microscopy (SEM) showed good dispersion of the BT nanoparticles in the EC polymer matrix at lower BT concentrations. However, at higher concentrations, the BT particles form a continuous phase or a "filler network" leading to weak BT/EC interactions. This finding is well supported by the results of the tensile strength and storage modulus. The dielectric properties of the BT/EC nanocomposites were investigated over wide ranges of frequency and temperature. The addition of BT significantly increased the permittivity (e 0 ) and dielectric loss (e 00 ) and improved the ionic conductivity of the EC. The electric modulus (M 00 ) results were analyzed in terms of the Havriliak-Negami function through three distinct relaxation mechanisms (namely a, b*, and b relaxations) in the temperature range 30-1508C. The dc conductivity (r dc ) results suggest that the BT/EC nanocomposites formed at low BT loading (up to 7.0 vol%) and a temperature of £ 608C are good candidates for antistatic applications while those formed at higher concentrations and temperatures are recommended for use in electrostatic dissipation applications.

“…Lead-zirconate-titanate (PZT) [24], Ba 0.6 Sr 0.4 -TiO 3 (BST) [4], and BaTiO 3 (BT) [2,7,8,13,15,19,22] are often used as fillers in polymeric composites due to their high e 0 values. Larger sizes of ceramic particles ($1-10 lm) lead to the existence of pores in the polymer composites [10], especially when filler loading is close to 50 vol% (f = 0.5).…”

“…This is because these materials have potential for many applications in modern electric power systems and electronic devices such as capacitors [1,2,9,10,[15][16][17][18][19][20]. Because of the miniaturization of the technology and for embedded capacitor applications, high e 0 values are required for capacitor applications [1,21].…”
