Dielectric properties of <scp>iPP</scp> and <scp>aPS</scp> nanocomposites with core‐shell particles obtained by treatment in transition metal salt solutions
Abstract
<jats:title>Abstract</jats:title><jats:p>The dielectric properties of nanocomposites based on isotactic polypropylene (iPP) and atactic polystyrene (aPS) obtained by novel, simple, and environmentally friendly treatment technique have been analyzed in this study. The best treatment conditions to obtain nanocomposites with embedded core‐shell particles with enhanced dielectric properties were considered. Treatment of polymer matrices in water solution iron(II)‐chloride had the most pronounced precipitation effect, that was directly related to the appearance of higher transition metal concentrations in the iPP and aPS matrices, in comparison to treatments in the other two transition metal salts, MnCl<jats:sub>2</jats:sub> and NiCl<jats:sub>2</jats:sub>. Relative dielectric constant and loss tangent have been studied in the frequency range from 20 Hz to 9 MHz. Embedded core‐shell nanoparticles (from 15 to 150 nm in diameter) in a very small amount (1.72E‐8 mol/cm<jats:sup>3</jats:sup> to 1.17E‐5 mol/cm<jats:sup>3</jats:sup>) resulted in significant improvement (2.5% up to 9.1%) and stabilization of relative dielectric constant value toward higher frequencies and also lowering loss tangent in compare to starting polymer matrices. These properties indicate that materials obtained with the presented treatment technique can be applied as microelectronic packing and with further development of the method in order to obtain a higher concentration of metal ions as energy storage devices.</jats:p>
