“…The values of G and B increase at all the frequencies under study as a consequence of the Alq3 share (Figure 6). It can be concluded that the hopping charge mechanisms and matrix polarity are enhanced by the presence of Alq3 33,43–45 . Also, charge transfer complexes formed due to presence of Alq3, which was confirmed by UV–vis spectra, increase the components of AC electrical conductivity and can contribute to the photoconductivity of these composites 34–36 …”

Polymer composite films of tris‐(8‐hydroxy‐quinoline) aluminum (Alq3) and polymethyl methacrylate (PMMA) at two different concentrations were investigated. Dielectric properties of the samples were measured in broad frequency range and results show an increase in specific conductance and susceptance by adding Alq3 in PMMA. Changes in dielectric spectra caused by irradiation of the samples with LED lamps at different wavelengths were also recorded. The samples were examined by UV–Vis and Fourier transform infrared spectroscopy. The interaction between Alq3 and the polymer matrix was observed in the photoluminescence spectroscopy spectra. The doping of the PMMA with different concentrations of the Alq3 leads to the unique photodielectric properties of the resulting composite, and that is the main result of this study. Due to its interesting optical and photodielectric properties, PMMA/Alq3 film may find application in solar cells and optoelectronics.

“…Polyolefins, polymers composed only of carbon and hydrogen, are cheap and environmentally friendly materials for making batteries. Isotactic polypropylene (iPP) is a polyolefin that finds application in all branches of the industry due to its suitable thermomechanical, chemical and electrical (insulation) properties [11]. A more detailed insight into the economic aspects of the application of rechargeable batteries, on the example of an iPP/metal capacitor and the electrochemical batteries, is given in Table 2.…”

The price and environmental aspects of electricity storage significantly affect the application of green technologies. The electrochemical batteries are currently the best choice for storing electricity for most industrial needs and products. Polymer capacitors show very low energy density compared to conventional batteries and therefore cannot be widely used for electricity disposal. At the same time, all other features of polymer capacitors that characterize battery systems are ideal. After a brief comparison of the basic properties of electrochemical and physical batteries, this paper presents the influence of electron trapping on the energy density of a polyethylene capacitor. The presented results indicate that the phenomenon of electron trapping in polymers can increase the energy deposit of polymer capacitors.

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, MnCl2 and NiCl2. 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/cm3 to 1.17E‐5 mol/cm3) 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.
